I created a world and let my friends join in on the fun. 4 people total
2 picked the wrong hearthlings for the biome so i helped them out by removing their kingdom via the multiplayer menu and let them rejoin. After this my friends joined forces on 1 kingdom. i do not know how or what happened but basically friend1 couldn’t create his heartlings but joined instantly and joined in on friend2, now they both have 1 kingdom that is fully functional and they can both do anything they want. 20Min later and no game breaking stuff happened. pretty weird but funny.
