I really hate to keep adding more work, but I just found a softlock in the invasions system (forest). No clue on the trigger, but continue and auto both kept duplicating my rabble and infernal troops as well as the travelers, leading to a massive war between thousands of troops and travelers with no one doing anything. The only escape was to close the game. Was around 2 weeks after unlocking the infernal melee, maybe a few more.
Thank you for the reports! I've returned from my family visit so I'll get to work on it.
Don't worry about adding anymore work. Honestly, it's greatly appreciated, I try to test everything myself but you'll always miss something.
And thank you for playing it, I'm honestly baffled and just laughing and smiling write now that someone did. Thanks!
