I was working on a combat map today, and because I had used an NPC with a modded mech, I set it as a requirement. Now I can't reopen it due to a version mismatch. Is there anything I can do? If not I'll just redo it.

nvm i figured it out! I am stupid (for future reference, check the "editor_autosaves" folder).

Interesting, I hadn’t thought through it locking you out of additional edits once there’s a mismatch. I’ll make a note to find a way to resolve that from the outside of the editors. Thanks for flagging it, and I’m glad that the autosaves resolved it for you.
