There's a bug that happens on some peoples' computers, but not all, where the log button crashes the visual novel if you press it. It usually happens further in but it's still being figured out. Hopefully this announcement will be taken down once it's fixed. It's really weird. If this happens to you, press "rollback" to go back and you can continue the visual novel, but the log button might not work. Or it might. My half joke is that maybe some are cursed and the curse is distributed randomly. The bug is a work in progress. Sorry for any inconvenience.
