Is it stopping after finishing all of the event or is it stopping at a specific spot?
With just going off the pictures the fact that 0x2 and 0x68 both being Deborah might have something to do with it. It might be trying to put a frame on a character that doesn’t actually exist on screen. Try changing the 0x68 to 0x2 or vice versa.
If I were to guess, I would say somewhere in your editing process you broke the games internal code. The game only loads the chapters upon starting a new game. After that if I try to restart the chapter, the game freezes and cannot even recognize the script. I have never experienced this problem before. I recommend you create an error report using FEBuilder, and submit the report on the FEBuilder thread: FE_Builder_GBA
Are you patching with FEBuilder? If so, I get similar kinds of errors as well that bork certain functions. I expanded weapon icons and used the patch to fix the bug with using item icon IDs past a certain point and it completely broke all staff healing. What seems to fix this is going to the area FEBuilder blanked out at the location of the old data and pasting back the data from a clean ROM so that it looks like no edits were made in that section.
Some other patches seem to mess my game up as well, so having back-up copies from before patching helped me identify the source of the problem.
Not really sure if this information would help you, but I suppose you could try seeing if FEBuilder 00’d some data and pasting back the original data from a clean ROM and see if that works.
