So in investigating something related to the bonus collect, the ‘no bonus flips’ setting if set to kill the flippers, also kills the bonus collect routine prematurely sometimes… so a simple work around might be to just allow bonus flips.
It’s still not certain what causes the core error.
do other games have bonus flips bugs when off?
Not that I’m aware of. I don’t know 100% that this is what causes this (or a combination of this and the reuse of the temp locations). The biggest puzzle is figuring out what causes it before attempting a fix. If it was just the bonus flips that would have been nice, but again… without knowing how to trigger it…
