Thanks for the bug report. Looking at the stack trace it seems we don't handle the case where, for some reason, an empty single line python statement is present. I didn't know ren'py allowed those, interesting.

I'll push a fix soon.

I've pushed a fix in 07b3d03 for this issue. Could you confirm that it resolves the issue?

shahidcodes commented 5 years ago

Yeah I was able to decompile without any issue. Thanks @CensoredUsername
