The chances that I cause them are at least equally as high as my experience in the Civ4 DLL code is still low so overlooked connections can happen (I had not done any real Civ4 modding before C2C).Edit - this isn't aimed at anyone or any specific change BTW - it's just that we're seeing a lot of hard-to-pin-down CTD reports recently. Most likely they will turn out to be my fault, but the point is that chnages all have risks and we're pouring a lot of changes in currently.
A freeze period sounds good. That way the releases will be more mature.
