Odd Error right before loading the map via compile

Right before its about to load the map for a quick run-through to check stuff, this error came up.

Host_EndGame: Map coordinate extents are too large!!
Check for errors!

I dont really know what that means. I dont have too much stuff up really, its just the beginning of the map, the 1st CP isnt even set up yet, this is like, Day2 and Im already getting owned by odd probs . The sticky didnt say anything about this, so any help guys? Or should I post my whole log?

I'll check later tonight, its Halloween, gonna be busy with peeps

Im guessing its the vertex tool, I made a ramp that goes up at an odd angle, and put a wall to it, which may be the prob. Ill check, thankd guys
