Not sure where else to put this. But in case it hasn't been mentioned yet. Whenever you get swallowed by (secretary) pred. Bring them out to battle, while still in their stomach. Then use the sandbox mode while in battle. The game hard glitches upon your return to base. Making it so that you can never be swallowed by your current secretary. Even if you change them out for a different pred. Go out for another battle. Nothing seems to fix it and your locked out from being swallowed ever again. Thankfully this is still in demo phase so hopefully it can be fixed before full game releases in the future. (Though I also somewhat doubt sandbox mode would even be around. In full release, as it's obviously rather game breaking.)
