I'm trying to start the mod, but it crashes after trying to load episode one and I get the error
MAP33 - Space Cat
Line 540 has no first side
Execution could not continue
Could Not Submit command buffer: device lost
EDIT: Okay it works if I turn off Vulkan. Is that supposed to happen?
Space Cats Saga+ (1.4) New Weapons and Overhauls

Got a cool project idea but nothing else? Put it in the project ideas thread instead!
Projects for any Doom-based engine (especially 3DGE) are perfectly acceptable here too.

Re: Space Cats Saga+ (1.4) New Weapons and Overhauls
seems to be a problem with gzdoom. had that only a few times and i am working with it for 5 years by now. switching to openGL should fix it. you using latest gzdoom version?

Re: Space Cats Saga+ (1.4) New Weapons and Overhauls
It would certainly be nice if GZDoom wasn't crashing, but the error message is correct. Line 540 on map33 does not have a first side - and it should. It actually looks like a vertex on the corner of the sector was accidentally moved, creating line 540 which just kind of sticks out into the void.

Obviously, that should be an easy enough fix.

Re: Space Cats Saga+ (1.4) New Weapons and Overhauls
this seems to be a bug with vulkan renderer. switch to opengl and it shouldnt happen. the missing linedef shouldnt be a problem
never really had any problems with space cats. it works with most mapsets and addons.

im working on the next update all this year, before release i will take a look and try fixing most things. but none of them should cause any problems.
