I am not sure which mod it is, but I was getting blocked from using Free Experience to purchase Field Mods. It started with Patch #4 (Sat/Sun) and was happening again in Patch #5. I'm also having a quick freeze (1-3 sec) issue in-game.
I contacted WOT Support and they suggested Safe Mode to disable mods. When I launched Safe Mode, it all cleared up.
I am not sure what mod(s) are causing the problem. I've attached my complist. I plan on reinstalling with a lot less mods to see if it clears up the problem (maybe a conflict between two or more mods).
