Shoveling shit was never meaned as a way to level up. It was just a needed 'feature', after our Brahmins learned to create shit.
Still, tb is very buggy in the moment.
If you want to make enemies, try to change something.
Im sure you have heard this like 15682350^53 times BUT: Is it possible to decrease NPC turn? Instead of giving them 30 sek, give them 15 or something :/ Or is their turn connected to ours so if you decrease their our will also be decreased and seperating them would just mean shitload of extra work? If so just skip it
