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

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.

Re: Space Cats Saga+ (1.4) New Weapons and Overhauls
Any news? I hope this is still being worked on. I've been playing Doom mods on and off for over 25 years now, and this is still my all-time favorite Doom mod. It combines so well with other great map sets too. I can't wait to see what comes next for this project.DerTimmy wrote: Tue Nov 04, 2025 11:51 am this seems to be a bug with vulkan renderer. switch to opengl and it shouldnt happen. the missing linedef shouldnt be a problem

I'm still waiting for the mod author to complete his project. It's very global.
