Found a few more crashes, first one a ways into the scene "Dream of a distant utopia" on the second day at the temple, another one happens when trying to change the font, and the last one happened when trying to look at the item description for the "spoon from Taizan" in the bottom right corner of the item collection in illya's castle, though it didn't save getting the item so I haven't been able to reproduce it.

Also, not exactly a bug, but I've noticed the default font is missing a lot of special characters. An easy one to see is near the end of "Towards the "splash"" on the first day at the streets, where there's a missing Celsius symbol, though there's also been a few missing characters in the hanafuda minigame and in the fortunes. Not a big deal overall, just seemed worth noting if it hasn't been already.
