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

Could someone explain what this means? My map doesn't have any leaks now but I get this error when I go to load it in game :S

EDIT: In the compiler it says,

Brush 5266: bounds out of range

Look for that brush and either resize it or delete it, Like the error says, its too big.

But how would I know what brush is number 5266?

But how would I know what brush is number 5266?
