With Celebrations & Pets macrotastic is causing sim resets during dancing and a few other actions. When I remove macrotastic testingcheats doesn't report any errors. Is it possible another hack is causing macrotatics to fail, but so no signs when macro isn't installed. Or does macrotastics have problems with Celebrations?
Celebrations breaks the engine-detection, because its bits say it comes after Seasons, but it doesn't, so it's broken. Some method of coding a messy kludge to fix it is being looked into. Celebrations without Seasons is not a presently supported configuration of game due to these issues.
