Taxes don't get synced, it would be a great help if the date would be synced, sometimes the population is completely out of sync and one player unlocks a milestone about 3 minutes early and most importantly: Sometimes, after about 10 minutes, the money just starts going down like crazy beyond recovery (-200k and decreasing). Also, but i dont know what you can do about that, when you use e.g. anarchy mods to place some stuff where it doesnt belong or place bridges with mods where normally, there wouldnt be a bridge, it looks super broken for the other players
