Hello there.
First of all, I'd like to thank this community for all the time spent in making this great game even more awesome.
I'm not sure if this is the right place to ask for help regarding crashes, so I want you to excuse me if it's not.
I just did a clean install for the second time in a week, and with clean I mean uninstall and install from steam, before unloading the mod pack with BWS. Both times I went into crashes problems, the first time I couldn't find what was doing the job but I've found what is doing the job this time: I've just picked up Jan, and whenever he tries to start talking with me for the first time after taking him the game freezes.
Since my game is in Spanish, I tried to change it to English to see if it worked and it did for a part. I resumed my game and this time Jan could start talking with me, although all I could see was "Invalid XXXXX" messages. After those lines, I saved my game and went back to Spanish just to see it crashed from the start.
I'm not into modding at all, save for the "install, select options in BWS avoiding red ones, play", so I'll try to do my best. Please find attached both my WeiDU log and my save files, just in case it helps:
