I ran into this issue that then ran into a bunch of others after hitting ignore (this was after choosing not to do what comes up in the shop and occurs a few lines after exiting said shop on the 10th).

Yeah, this is unfortunately a bit of a bug with the Android build, which I will be rectifying ASAP. Tom (the creator of Ren'Py) has advised that the latest version of Ren'Py should fix this issue, and I will be releasing an update soon with this fix. Think of this future version as 6.5.1.
The unfortunate part is that I don't have an Android device myself. My family do, but they'd object to me using their devices as test subjects.
