Not sure if this was recently patched or not, but I just played Chapter 8 and the objective said "Seize the gate" but when I went over there with Aligmas, nothing happened. I tried everyone I could think of and nothing worked, but the chapter ended when I killed all the enemies. Just thought I'd point that out in case it wasn't patched! I did mess with my ROM a bit, but I only looked at palettes and characters, not maps, and I didn't mess with Aligmas at all so I don't know what the issue is.
EDIT: Okay while playing through the next couple chapters, it seems that for some reason the map objective is displaying the NEXT map's objective. Chapter 9 was a "Defeat Boss" chapter but the objective was actually to seize the gate. Also the Chapter 9 boss death dialogue was replaced with a glitchy version of the intro dialogue of Vlad's first chapter (Forget which one it was, it's the first "x" chapter), but Vlad's just talking to himself. If anyone has a fix for this or if it's already fixed, please let me know!
