Steps to reproduce:
1. Train a henchman in a fortress. He comes out at level 2.
- he gets to pick two level up traits. Both of them list level 2 as the level he has leveled up to.
Expected result:
At level 2, he should get to pick only one level up trait.
p.s. Thank you for fixing the bug where they don't get to pick any traits. It works better now, imo, but still not completely correct.
