> Hmmm... so in the process of trying to track down exactly where the write was failing to the reloadbasic output file, I happened to add a `print(self.file.tell())` and suddenly the bug went away.

I'm still using Python 3.11. I had a look through the changes in 3.12 and notice that there are changes to the GC. I also notice that `DelayedFileWriter` creates `FileMarker` reference loops. reloadbasic.py doesn't actually flush or close the output file but instead dodgily assumes that it will be closed/flushed to disk when the program exits, when all variables are finalised. It turns out that this worked in Python 2 but is not reliable in Python 3. The reason being the reference loops: in order to clean them up the GC has to break references between objects and it can break references inside the file object, destroying the buffer without flushing it. See https://github.com/python/cpython/issues/62052#issuecomment-1578053631. There is a warning in the documentation (which was fixed [here](https://github.com/python/cpython/pull/23135/commits/f4bbc4fcafb17da315fbaff662ff5bfa8ff93065): you have to close files, not just delete them).

It's meant to work if `OHRRPGCE-Game.app` is next to `OHRRPGCE-Custom.app`. Anything in c_debug?
