Calendar messed up after GrowTog and patch

Took all mods and cc out, cleared the cache folder and file, gone into some old saves so I don’t corrupt the newer ones. HSY events seem to be alright but most of the CoL fairs are gone, as are some of the SE festivals. Put MCCC back in, along with the map replacements and XML injector test package, and bingo, the calendar is messed up again. Most of the HSY events are back to normal, so it’s still the other packs that are a bit weird there, and Winterfest is now in Summer! So it looks like MCCC is the culprit but since I have the most recent version, I don’t know what to do about it!
