Infamous T-Pose after running FNIS

[xllKeineAhnunglx]

Hello,

first off, I am not an expert on this, so please excuse any dumb mistakes I may have made.
So, as for what happened, I installed "Animated Feathered Wings SE" (https://www.nexusmods.com/skyrimspecialedition/mods/11536) and "Real Flying SE" (https://www.nexusmods.com/skyrimspecialedition/mods/18347) as a prerequisite to "Animated Feathered Wings SE". First, I forgot to run FNIS and just loaded up my save and tested the mod (animations seemed to be working though). However, I noticed that the flying feature of "Real Flying SE" wouldn't work and I remembered that I forgot to run FNIS (which, in hindsight, shouldn't interfere with the feature itself I think?), so I closed the game and ran FNIS.

Here it starts to get a bit messy, I how you can follow. When running FNIS, I would get an error, stating that there were to many animations (even though I had the XXL mod installed), so I deleted the XXL mod and reinstalled it. After that it was fixed, however, after running FNIS again, I got the following warning (no other warnings or errors): >>Warning: \character\behaviors\FNIS_FNISBase_Behavior.hkx not Skyrim SE compatible<< . Not really thinking to much about it, I loaded up my save again, and I'm not sure if this warning is actually the cause for it, but now ALL characters were locked in the T-Pose, no animations at all. Now, regarding this warning, I know it refers to something being a mod for Oldrim and not Skyrim SE, right? While I cannot say that I am 100% sure I have no Oldrim mod installed (just fairly certain since it worked before), I also cannot tell which one it is supposed to be. Does the "\character\bahaviors" part refer to FNIS Behaviors itself?

I appreciate every bit of help I can get. Thank you in advance!

Sometimes I really wonder how beginners manage to mess up an installation, but they are really creative in this respect. :)

 

You have mixed 2 FNIS versions. While you are running FNIS for SE, you are using at least one file from FNIS for Oldrim (the one from the warning).

Well, you were, of course, absolutely right. After checking every FNIS file again, I noticed that I accidentally downloaded the Oldrim XXL file when I was reinstalling it. Thanks for the quick response!
