While playing on Pokemon Alpha Sapphire V1.4 USA game cartridge on the latest version of Luma(v12.0.1), I tried to use the bypass walls cheat outside on a route and my game crashed. The cheat sometimes crashes and sometimes doesn't. I notice that it crashes when I turn it on when outside on a route and I immediately walk/run around after activating it. It also sometimes does this in buildings.
Here's the crash dump(shared on that website because I can't upload here):https://pomf2.lain.la/f/w2zgpwqy.dmp
Cool plugin though!

Sometimes works in Pokemon Y, works inside some buildings and Lumiose city from what I can tell but it doesn't work outside.
