When In-Game, Wrong Texture Appears

Hey guys, I couldn't find this in the search though I didn't really
know what to call it. Here's the problem: In 3 spots on my map
the wrong texture is popping up. (its a cs:s map btw)

Case 1) Right around a door theres a stone wall, this shows up in the
editor fine, but when I play the map that whole area is now the door
texture.

Case 2) I have a hallway with rooms on one side. All the rooms
but the room on each end are the same. This is fine in the editor
but when I'm in the game, half the rooms floor's become the same as the
one on the end.

Case 3) Same exact thing as 2 but on the 2nd floor. This time
though, they all get the hall of mirror kidna thing like I was staring
at no draw textures.

Thanks guys. If you need pictures I can do that. Sorry if I couldn't find this.

Post your compile log....

For some reason I can't paste... Well I'm looking through it and I
don't see any Error's or leaks, only word that looks bad that pops up
is "warnring", which is in 4 lines. that section goes like this:

ProcessBlock_Thread: 0Brush 43410: WARNING, microbrush

Brush 43412: WARNING, microbrush

...1...2...3...4...5...6..Brush 16387: WARNING, microbrush

.7...8...9..10 (1)

ProcessBlock_Thread: 0Brush 43410: WARNING, microbrush

Brush 43412: WARNING, microbrush

...1...2...3...4...5...6..Brush 16387: WARNING, microbrush

.7...8...9...10 (0)

Well seems that you have some microbrushes. I don't know what the do
but i know they're bad. I suggest you delete them and create new
brushes. Also check if those brushes are the same ones that's screwed
up in your map. If they are, you know for sure what's wrong.

How do I find which ones are the ones listed?

Check for errors in hammer [alt + p] to see if you have any errors,
also did you change these 3 textures after your last compile, it could
be that something you did since your last compile has screwed it up and
it's loading an older version.

Press CTRL+Shift+G or select "Go to brush number" in the view menu,
then enter the brush number. Then, the brush will be selected.

BTW, microbrushes are ones with a volume smaller than a certain value
(1.0 cubic units, I think). You tend to get them if you've scaled down
brushes. The reason they're bad is because they can cause leaks and bad
faces / rendering errors in the final map.

Thanks to you guys collectively I was able to fix it up. It
turned out I had microbrushes ontop of the actual floor somehow.
In any case I deleted them and now it's fine. Thanks guys.
