Yeah, it's something we didn't catch. I believe it's only on the Android version. Something to do with old saves and the Phone UI. (Though I'd be interested to know if this was also on the PC and Mac versions.)
I don't play the android version, pc only. I'll play through it again from the beginning to make sure but this happens all the time in other projects as well so I think its just that Ren'py doesn't like version differences when loading up old saves. I'll be sure to keep that in mind when and if I actually make my own. Thank you and already cannot wait for the next update. ;)
