weird bug

[zyxstand]

Today I had my server running like normal and when the server did a '/nextmap' the thing spit back about 80 times the message:

Error: Could not load map (my_map's_name)
Map load error 32

It usually pisses me off cuz changing maps won't fix it - I have to redo the server...
This time however I wanted to investigate what it does - afterall, the map seemed normal on my screen...
I realized that the server didn't have any polygons in it!  They showed up on my screen but didn't register in server.  I fired bullets like normal and they were stopped by walls - but only on my screen:  I was able to kill people through walls!  Also I realized that when people stopped moving the server takes over their positions (which makes sense because when a player gets a lag-spike the server temporarily renders his position till client can respond) - so it showed the player warp through floors and stuff though very weird.
Also, I had BE turned off (cuz it causes too much trouble).

Any idea what causes this error?!
So when other people stop moving they warp through the floor

Have you compiled the map?

well the problem happens at random, it seems.  I was playing with 2 other people for a few rounds (with some map-changes) and suddenly, on a map change, this bug happened.  Of course I complied the map - I've been playing with that map for many rounds...
