hey @Metaxona thank you for the report! any chance you could share a repro for this?

If the code being flattened contains do-while blocks than I probably know what might be causing this, but otherwise a repro would be very useful here

yeah it does indeed contain a do while loop, several of them. though I am currently not able to share the repo since it's a private and not a personal repo

but i did use do while loops in-place of all or most for loop applications
