For Braves with us since Early Access, With the addition of new difficulty settings, we have identified a bug in the game that would only affect those who unlocked Challenge Tier 10 before the Full Release. Specifically, please avoid entering the "Marsh Keep" stage in Challenge Tier 1 - 9, if you have previously unlocked it in higher Challenge Tiers. This issue will only appear and affect players with a saved file that unlocked "Marsh Keep" stage prior to the Full Release. Our team is working on a fix. We expect to have a patch available soon! We apologize for any inconvenience this may have caused and thank you for your continued support and patience. The Dev Team
