After updating several mods (Arms Race, FWE, MMM, Ling's) along with the necessary FOIP packs, upon reloading my save I constantly am getting 3300XP. Time and time again. Apparently some quest trigger hands out 3000XP all the time, though the only one I could find doing this was in Arms Race - but deactivating that one does not help.
I'm completely puzzled right now. Can I somehow log and track where those XP come from? The console does not show anything.

Load order as following, in case the sorting tool did something wrong.

If there's something else wrong in there - just point it out, I'm not picky when it comes to help. Especially the FWE/MMM thing might need work. ^_^
