Finally got around to sorting out RC2.
This should fix the issues people were reporting, except for Armani's issue. However I've added some code that should at least help us narrow down which file the issue is happening on, and maybe even figure out the exact cause. (It's also possible the GR32 updates in the meantime will have fixed it, I can't say. If they haven't, this build should at least help narrow it down.)
https://www.neolemmix.com/download.php?id=589Changelog from RC1> Added some extra logging for when PNG files fail to load.
> Added some recent contributors to the credits in the scrolling text.
> Fixed bug: Laserer laser remains visible (but non-functional) if a laserer is killed by a trap / etc or begins teleporting while lasering.
> Fixed bug: The move/copy options in the mass replay checker may overwrite files if multiple inputs end up with the same output filename. (A number will now be appended to the subsequent ones' filenames.)
> Fixed bug: When in fullscreen mode, the start bar doesn't hide and NL doesn't quite cover the entire screen, if OS scaling is set to any value other than 100%. (This bug is exclusive to 12.13.0-RC1 and does not occur in 12.12.X.)
> Updated the version of GR32v3, which may fix some issues (in particular the issue with saving level images).
