You could also simply delete the events file of the map rather than the map itself. They’re two different files after all and deleting one will not damage the other. (Also possible to edit the event file manually but I would advise against this unless you know what you’re doing)
Yes, you are right, I discovered this when I was going to swap out the corrupted map for the new one. I did edit the file manually, and I was able to locate and remove the event entirely.
Oddly enough, I corrupted the layer file of the map as well, it had fragments of the map it teleported me to wedged in it randomly. This wasn’t a problem though because the backup version was on the exact same update.
