A few tips for playing with this mod. The mod is great but the game has a few glitches that can get you stuck. I've had to restart this game about 6 times and I think I've got it ironed out to avoid future restarts.
First, don't keep the mod on all the time, especially if doing something that will get you XP. Having the mod on while getting XP can cause you to jump into an infinite level up loop that won't stop until you turn off the mod. The resultant level leap will eventually cause you to get stuck on a renovation task later and you will never be able to move off of it, thus resulting in starting over. Just use the mod specifically when you need it and turn it off again.
Second, be careful about completing building chains up to the last one before the game is ready to use it. I've done this twice now (second time on accident) with the last part to the wizard's building, once you finish the building, if the game wasn't ready to use it immediately, it will sit there on your board and never complete the building even though the game moves on to the next area. What happens then is the items that you start merging to be able to level that building will clog up your board and there's no way to get rid of them so eventually you could end up with a full board.
Third, this last one didn't cause me to have to restart, but just from experience don't get every extra pack of treasures the game offers just because you can. I once inadvertently ended up with over 100 of the pet upgrade chests and it took me forever to clear them all out. Better to do that a little more slowly unless you want to sit there just clicking chests open.
