Do you use Thunderchild ? If so, i'm guessing you explored the new section that the mod creates in High Hrothgar and saved your game there. It's behind a door at the end of an hallway. For some reason you can't save inside that new area. There's another mod that adds a new area in the College of Winterhold (can't remember the name), and you can't save there either.

I have subtitles on all the time too. Just now i tried to turn them off and was able to play for around one hour without the bug, when other times it usually lasts 10 or 20 minutes. After that i used an alchemy station and the bug appeared immediately. I saved just before using it, and as soon as i activated it noticed some text missing and after that confirmed that the save was already "corrupted".

One thing that is noticeable right away (the only one i guess...) is the effect on dialogue boxes, i know almost immediately when the bug appears, if i speak to someone. I start a conversation and some of the dialogue options disappear while i'm trying to choose. Sometimes i can't choose the option i want, but with a bit of luck and if i try it a couple of times it works. For instance now i'm in the Dark Brotherhood quest line and i can start a dialogue with the NPC, but after choosing three or four options, the dialogue simply ends and the quest doesn't go on. I already know that it will only work and i will only have all the dialogue options, if i restart the game and reload the save. In mods with new quests it's even worse, usually i can't even start a conversation with the NPCs, but after restarting everything is fine. It also affects any popup message boxes, like some books, in-game mod settings, etc. Some of the text simply disappear. Any clues on why something like this could affect the message boxes ?

I don't use anything like that.

What about steve40 ? Author of skyBirds. I didn't play Oldrim but i saw some old topics where he tried to solve some problems with papyrus logs and other stuff.

I like the weather change possibility, it makes some sense and it would explain not happening in a new landmass. Creating a new save would make some sense too, but the files still get "corrupted" even if you don't make any save in those 20/30 minutes.

I just confirmed that i'm able to play for as long as i want without any save corruption in new lands/maps. I played Falskaar for a arround 3 hours, saving, loading and doing everything i always do in the game, without any issue. But the second i've returned to the main Skyrim map, the corrupted saves appeared again. All the mods are still there but in a new map there are no problems, and no play time "limit" before the corruption. So i guess something in Skyrim world, or in the way that some mod interact with Skyrim world, is triggering this after the usual 20/30 minutes of playing, but only there.

I deactivated Frostfall + skyUI 2.2 and continued to play with the same save. Haven't got this issue for ~3 hours. Enabled skyUI and got it again in 20 min... Gonna try QD Inventory SSE instead to see if there is any difference. After you try that tell us if it happened again please. I never had Frostfall, but yesterday uninstalled skyUI and installed QD Iventory right away, and it keeps happening. Ok, I was wrong, It still happens with and without interface inventory mods... Just to be sure, when you played those 3 hours without issues, do you remember if you were playing some mod with a new location/new land ? Or just regular Skyrim quests/map ?

In the "suspects" list, i don't use Immersive Patrols, Immersive Followers and Eli's Breezehome. Also already had this issue before installing Helgen Reborn and Skyrim Underground.

I use skyUI too. But i think it was already happening before installing it. But i'm not sure. Wich version of Qaxe do you use ? 4 or 5 ? Did you upgrade it ? From the "suspects" list i would point to RDO, Immersive Citizens, maybe Travellers of Skyrim or Qaxe, but who knows...

Do you use LOOT ? I have a lot of the same mods but a very different load order, i had for example Qaxe Questorium or Rigmor down in the load order, but now i just let LOOT do his thing. About the followers i don't know, i will have to try without them. One thing i did noticed is that in some of the new quest mods, if there are new locations i can play a lot longer without the corrupt saves appearing, and as soon as i'm back to the regular map, it happens. I don't know if that's happening every time, but i've noticed it at least a couple of times. It definitely happened with Qaxe Questorium, in Icicle Valley. Wich AFT do you use? http://www.nexusmods.com/skyrimspecialedition/mods/4340/? or http://www.nexusmods.com/skyrimspecialedition/mods/6656/?

I have the same problem, and also a lot of mods that you two use. But i don't use those two oldrim mods, neither Immersive Armors. I've suspected of Wet and Cold, and ended up uninstalling it, but it keeps happening, even in a new character/new save, so it's also not a problem originated by uninstalled mods. I don't use Achievements Enabler, but i did use the console a couple of times. Maybe something with AFT (i had iAFT before, and now i'm in my second AFT, this one properly ported for Skyrim SE). PS. Also i cleaned everything i've uninstalled with Skyrim Tools: http://www.nexusmods.com/skyrimspecialedition/mods/5031
