This is what popped up after entering the den and fighting a wolf. Idk if this is the error you were already talking about. But better safe than sorry.
oh, I almost forgot. That same error I shared continues with the wolves you fight after leaving the den. You have to restart it and avoid the den, otherwise itll just repeat itself. As far as I know, mining is still okay π
Do you have Discord by any chance? I should have fixed the error causing that but I would like to DM you for more info, and possibly provide a test build.
