The game’s crashed for me during Chapter 13 during enemy phase. I had to manually close out the emulator. Resuming just made it happen again and when I tried replaying the chapter it crashed again during enemy phase. Both times it happened around 7 turns into the map and always at the start of enemy phase. Some of the map sprites glitched as well when it began to happen. I’m playing on mGBA.
Ill look into it today to see what causes that, as im currently playtesting to look for issues still. Ive always had no issues on chapter 13 til now, ill take a look today. Ill be putting out a new patch soon to fix some small errors on my part anyway.
EDIT: Had a quick look, didn’t crash for me, what mode are you playing on? I had a thought it would be to do with reinforcements that show up but thats turn 8? Also what version of Mgba are you using?
