I get occassional, semingly random CTDs with 1.3 that I don't remember from 1.2, they're not too bad but they shouldn't be there anyway.

And then a problem I've had before and got again yesterday. I build a fort with an army and it's screwed up, it's supposed to be a wooden fort I guess but it has two yellow dots indicating it's level two, it can't be upgraded apparently(or does that require a certain tech?) and every fight happening in it, no matter who is inside and who attacks, causes a CTD. I don't think it happens to every fort I build though, just one out of ten or so.
