Ah, I see the problem. The starting conditional in question is k_ptar_rukil10+. Not sure which one it is, but you are using a mod that is editing tar_m04aa.mod with an old version of TSLPatcher that has a bug that causes it to delete any files with characters like + in the filename when it repacks the MOD. This issue will affect multiple modules throughout the game, as Bioware used that convention a lot. One example from experience with my own mods is the Upper City Cantina. K1CP uses a fixed version of TSLPatcher that resolves this bug, but Fair Strides never publicly released it as far as I am aware, and it's only a few years old anyway. The only way to resolve it is to start again from a completely fresh install and replace every single mod's copy of TSLPatcher.exe with the one from K1CP (renamed INSTALL.exe) before installing any of them.
You'll want to go through your mod list and see which of them (aside from K1CP) edits tar_m04aa.mod and inform the author/s of the issue and the solution.
