I didn’t know Necromancers still existed
Anyways on that note, there is a thread here somewhere actually many threads (too lazy to search for them atm, I believe this thread also goes into some detail) that describe why it works the way it does in great detail.. Basically the tree/crop growth ticks afaik only occur when the weather changes from rain to sun or sun to rain which is why they appear to grow at such a slow rate, this is also why they will not grow during winter because it “snows” instead of “rains” which doesn’t count as a growth tick when it switches to a clear day..
As far as the trees go, they seem to take a very long time regardless of your day cycle settings or ticks because well they're tress haha.. in general they just seem to take ages to grow, but you can also modify that if you look at the cm_forest_maintenance.xml file in the data directory on your server..
Afaik this is correct, if anyone who knows more than me cares to chime in be my guest, I just figured I’d answer you since the forums are mostly dead lol..
