CTD on Save (Research & Speculation Included)

[KnightBlade2]

Skyrim SE has been very stable for me except when saving. With a lot of mods installed, it often crashes to desktop when attempting to save. In case anyone wants it, here is my Mod List.

Relevant info:

• I use LOOT to organize my mods and ReSaver (from FO4Tools) to ensure my saves are clean.
  
• I've tried checking papyrus logs but I don't see anything obviously causing a crash.
  
• Saving in a small cell, such as an inn or coc'ing to UnOwnedCell, the save occasionally works. It rarely works in a large or exterior cell.
  

Theory:

I believe this is related to the number of scripts somehow. Disabling a mod or two doesn't stop the CTD on saving unless that mod contains scripts. Disabling any mod with scripts allows me to save, at least for a time. (BTW, I know removing mods mid play is dangerous. At this point, though, it's the only way I can continue to save my game.)

Generally, this works for a few hours of game play. Then the problem starts happening again. I remove another mod with scripts (and clean the save file) and I can save again.

So, is there a limit to the number of scripts that can be running at a time? What about script instances or strings?

So, I'm hoping someone recognizes these symptoms and has some helpful information.

How big are your save files getting?
Try going into the save game location, and making individual subfolders for each character/playthrough.
Leave only the last 5 hard-saves and the 3 auto-saves in the main saves folder to continue with that character/playthrough.

 

The fewer number of saves overall, in the main save folder, 'should' reduce the instances of CTD on save,

as it will not have to read/load through as many files.

 

It will also be less cluttered, although with a few extra steps to change to a different character/playthrough.

Scripts Are the bane of saves.
If you uninstall or install new scripts in the middle of a playthrough, they are hardcoded into the saves.
Scripts should only be added before starting a new character or playthrough.
If you remove a script in the middle of a playthrough, it will most likey cause crashes,

as that script is still being called for from the saves.

Try using mods that don't use scripts, whenever possible.

A.F.A.I.K. the number of concurrent, running scripts is only limited by your hardware.

Also try not to mod the game in the middle of a playthrough.
Adding mods is 'usually' okay, but removing them can cause serious problems.
Even if you clean the saves.

Make a list of the mods you want to keep, for your next playthrough, and have only

the ones you know you want, for your next playthrough, so you don't have to uninstall

in the middle of a playthrough.
