I'm not even sure what kind of error this is...

While working on my map, I ran it to see how it was shaping up. Little did I know I was loading up Dance Dance Fortress with this massive disco floor. It's not even split into that many brushes. Alt P finds nothing, Interlopers shows nothing wrong on the console, and the game is running an old version of the map for some reason.

The game console shows me the error "vis decompression overrun" a few times, but I have no displacements, no super-detailed brushwork (especially in the old version it keeps running) and no 3d skybox brushes.

Compile logs help. Also check for leaks.

the game is running an old version of the map for some reason.

VBSP, which produces the BSP, is failing. The rest of the compile is using the old BSP.

I'm under the impression you already saw this page. Yes, you have too much vis data. I'm guessing the line in VVIS that looks like this has the number you want to make go down.
Code:
visdatasize:1365714  compressed from 1449472
This was from a map where I hit that limit and had to trim visdata. Maybe you have too many visleaves, they're too complex, or there's something else that's undocumented. To see what visleaves VBSP is generating, in Hammer you can go to the toolbar and select Map > Load Portal File.

Can you share a picture of how it looks in editor?

And just as quickly as it broke, I fixed it. I had to rename and resave the map because it was compiling but pulling an old .bsp, and had to delete a pesky door that was "out of bounds" or something.

I got it fixed, but here's what I'm working on if you wanna know. I probably shouldn't texture while I'm still doing brushwork but w/e, bad habbit. I'm new at mapping. Sue me :p

Yeah sometimes a file rename is all you need. I had this happen to me once before, glad you resolved the error.
