after playing through with a constant internet connection, here's a bit more detail:
the problem only occurs in choices about appearance (dragon, mordred, parents etc) and just had to be tapped a few times. I thought it was a save file issue at first but it'd persist even after reloading/restarting.
Then I tested on my computer with the same wifi and didn't have any issues.
Truly have no idea if it's just my phone, but I still wanted you to know
Thank you for your time!
