Maybe it's my fault ...
If you have installed my "HotFix" during the running campaign, it could cause problems (without new C-start).
This contains an SH4 experimental-adapted EnvMod of W_clear for SH5, which also contains new weather cycles and climate zones.
But no problem - I'm just making an update for the soup, where you have to start a new campaign anyway.
DLL is still in this hour ...
