Hello ! Sorry for the late response, it's the first time I'm encountering this error so I can't replicate the error... Thank you for pointing it out though, I'l try to look into it and fix it if possible (^ o^)/
Hello again ~ Sorry, I wasn't able to find or fix the error since you are the first person pointing it out and that I wasn't able to replicate it (u__u) I hope you liked the game either way, even without being able to log or collect the achievements O/
