Hello, I got this error message when I played. I'm using MGBA 0.9.3, if that helps.
"field 'valueOperator' is not accessible for type 'Modifier' using 'kind = 0'
I’ll try to debug it further, but this has been an issue for a while for some people and I’m still unsure what’s happening (I could barely replicate it, it may have been because of the emulators?).
I couldn't get it to happen on hardware, so I assume it is an emulator issue.
