Map editor very low draw distance

I've always wanted to make map mods but the editor is pretty challenging to learn. Recently I can't even learn though. The Mudrunner editor's draw distance is very low on my computer, only rendering about 2 "terrain squares" ahead of the camera. I've seen from youtube videos etc that this is not supposed to be the case, has anyone else experienced this and got a fix? Thank you.

No, it should be able to render the entire map, it does on mine. Tried verifying files, reinstalling from scratch (delete the editor folder FIRST) then uninstall.

Not quite sure what to suggest as it's not a problem I have come across.

PC Specs decent?

The problem seems to have gone away by itself. Fortunate for me but unfortunate for anyone else who has the same issue 😕
