[Solved] Can't run map with VIS
Sorry to bring back a solved thread, but I have a similar problem. In my map I am working on, I have been getting a leak coming from a point very close to the origin of the map, saying filter activator class leaked. The only filter activator class I have is in an instance well contained inside my map, I've tried finding the leak, copying the map to a new file, boxing the area, boxing the entire map, made sure radius culling was off, checked for entity bound walls, etc, no dice, so I am in need of some dire help. I am hoping this is just a dumb mistake and not something huge, but I hope someone knows what this is.
Thank you for your time

Camben, post the map so one of us try to compile. I've seen that sometimes some other can compile a map that the creator can't. Also some other can check your leak issue. 
useful tools and stuff here on TWP

Sometimes maps just stuff up. Copy and paste your map into a new file - sometimes that works.
I already tried that, it still didn't even work, the leak is still coming from the origin.
Ok, I get to it after school.
(Btw it has a very strange style, i tried to make it as un aperturish as possible while still keeping the walls, and it is a super heavy WIP. Also, should I post the instances I used?)

If they're not default ones: yes.
ok, its here. the error messages and white textures are there because they are custom and dont play a big role other than aesthetics. again, heavy WIP.
EDIT2: ok, something weird happened and it suddenly started working again after updating portal 2.... so, problem has been solved, i guess. well, thats good, and thank you guys for the responses still.

I can compile the map just fine. No leaks.
However I can see a lot of things that should be func_detail that are not. It will compile VVIS much faster if you do.
yea, apparantly it was something to do with the files hammer ran off had to be updated, check the editted post.
