@Tetrol88Using a manual LOOT run will override the results of the built-in Vortex LOOT routines, and disrupt Vortex overwrite instructions. I did this when I first changed over to Vortex, and found that I was getting a completely different LO. You should use the group assignments routine listed by @vortexposer.

If you haven't already read that particular book elsewhere, this is probably some kind of mod conflict, where the placed book has been altered somehow. You could try the More Informative Console mod to see if anything has affected it. Personally, I use Alternate Skill Books ( https://www.nexusmods.com/skyrimspecialedition/mods/25887 ), which has the effect of speeding up how fast your experience increases in that particular skill, making skill books much more useful, IMO.

You should use SSEEdit and run the script for finding files that can be made into light versions. It will tell you what you have to do to be able to mark them. Pretty sure that you will still have to start a new game to use them, and the changes may still break the mods, or any NPC head parts involved in the mods.

Well, just in case you haven't been banned yet, USSEP requires the latest version of Skyrim, 1.6.1170 as of this posting. That resource pack is part of that version, I believe. Buy the game.

Did you make sure that the external drive is formatted as NTFS? This can cause problems all by itself.

Having more than 254 standard .esp files in your load order can cause save corruption. Uninstalling all of those mods may just have brought you to a total under that limit. You could search on the Skyrim SE forum ( https://forums.nexusmods.com/forum/8877-skyrim-se/ ) for 'save corruption', 'corrupted saves', etc. You have to join that forum (Game Community) to post there.

Can't be of much help with your problem, but have you tried to alt-tab after you use ctrl-alt-del? Alt-tab should get you to a screen where you 'might' get to use the Tab key to select Task Manager in the list, or on the taskbar.

Something might be preventing the collection from installing it properly, since it has to be installed in a different location, separate from the normal mod installations...

You might get many more experienced views if you try to post this on the Skyrim SE forum ( https://forums.nexusmods.com/forum/8877-skyrim-se/ ). You have to join a game forum to post there.

Depends on your mod list - once upon a time, Beth disallowed dragon attacks in cities and towns, and several mods added them back, especially with mods like Run for Your Lives.

Maybe something in your browsers or your PC is blocking access to Cloudflare, which runs the captcha?

@That1guy1121Did you try verifying your game files? If you did, here's a long shot - look up the Alduin's Bane quest ID, use SSEEdit and put the quest ID into its search field, and see if anything is overwriting/changing anything in the quest, when you find its entry in the base game. I had hoped that a few of the modding experts would see and be able to help, I am just guessing here...

For SKSE64 mod compatibility/alternates, a recent list/spreadsheet is here on the Nexus ( https://modding.wiki/en/skyrim/users/skse-plugins ). Not sure how well it is maintained at this time.

This is a pretty specific problem, you 'might' get more experienced help faster on the dedicated Skyrim SE forum ( https://forums.nexusmods.com/forum/8877-skyrim-se/ ), rather than this general forum. Join that community to post there.

Did you ever look at Protect Your People here on the Nexus?
