I did make two custom henchmen, but I did play perfectly fine the whole session yesterday after making them.
Today I changed one of them slightly before trying to play [didn't hire them yet] which I guess could have broken the game?
Anyway I have uninstalled and downloading the game again right now and will try to launch the game without the custom henchmen and then try to launch with the custom henchmen before the change I made to them today.
