Don't worry, we're still progressing, slowly but surely :3 I'm working on the boss of the final dungeon of chapter 4, and after that and a cutscene, the chapter will be complete. Sorry it's been taking so long on this one chapter, but it's rather long compared to the others, and I'm still working on some gameplay bugs. Hopefully everything should work out soon.
About the Boret escape, sorry to hear the bugs are messing you up. There's some script glitch that seems to mess with the save files. I'm not sure what's the problem, but I'm pretty sure it's been fixed for the next version. About the spell, there's actually a limit on how many times you can use it (about 10? it's enough, you only need it ~5) so try not to waste it.
