Oh yeah, it could be. But then again, even playing these in any of the pre-LE ways is all over the place. Whether they work, have bugs, outright crash, etc. all depend on the game version (1.1, 1.2, 1.3, so on) and also the method (DOS, DOSBox, source port).

I think it's more due to Nightdive's editor. It also freaks out with RANDROTT levels

But yeah, thanks a lot for taking the time to convert and put these up here.

Weird, but I suspect I know why. When I first played/tried them, I got them straight off discs (disc images on archive.org and the like, rather). No errors, etc. Later when I went back to re-download everything to combine in an archive, I probably got a bunch of them from alt sources like ROTT fan pages; supposed to be the same files as from the disc but maybe some of the site hosted files somehow got corrupted.

Some of these levels have issues when converted to Ludicrous however I have found some of them that work and have converted them.

Oh ok, yeah. I can put it on my google drive. You can get it here. I noticed that a couple were uploaded to the workshop by others, so just have to double check you're not uploading a duplicate. https://drive.google.com/file/d/19uyLS1p2DFTWNAGKC0P5xHciRpJ3QuHq/view?usp=drive_link

Dropbox, mega etc.

Cool! How can I send you the zip with all the maps?

Sure

I see you're uploading quite a lot of the ones from the old days. Would you consider doing this for a particular set I have here? They're a collection of either insanely difficult or well done maps.
