Some final code requests (and screenshots)

There is an incorrect flag being set somewhere that allows you to go to Owzer's Mansion and recruit Relm, THEN go to the Cave in the Veldt and find Relm wounded

What you could do is use an unused event bit and set it when Relm is found in the cave. In the Owzen Mansion door event (dungeon entrance), check for that bit and continue event only if it is set. That would force the linearity you seek while not fixing the way it is already set, which I have a difficulty to follow.
