Also, as you can see in the video, the errors generally don't occur until after a cell change.
I discovered this when I attempted to add some new mods my save game. All of the mods in the load order below have been in my game I started the save, save for SKINNY SpaceSuit.esp ROCO_Sarah.esp. At first I assumed these errors were caused by adding mods into the middle of the load order already present in the saved game, so I tried moving I then tried moving all of the files to the end of the load order. This had no effect. Then I assumed one of the mods I was adding (all simple mods like 3EFhelmlessstealthsuit.esp, MalikaTheGypsyByAzar.esp, resetfollowers_v3.3.esp, or CoolLasersMod.esp) must be the culprit. To test this theory, I started adding one mod at a time, to see which one broke things. To my surprise, not a single mod on its own caused the the above errors. Instead, the errors occurred when there were exactly 206 mods or more loaded, completely independent of the content of the newly added mods. The newly added mods could be as simple as a single static record, and nothing else, and the errors would still occur as soon as 206 mods were loaded. I then tried starting a new game to test if this was an issue with my save file. However the errors appeared in a new game as well, as long as 206 mods or more were loaded.
Thus I have absolutely no clue as to what could be causing these errors. Any suggestions?
Note: Archive Invalidation Invalidated is installed.
Note: Before I I tried adding the mods, something similar with regards the the missing meshes/textures would occur after playing for a while/fast traveling. However, this was simply solved by saving and reloading.
