I've started getting the following error which I normally would have little difficulty fixing -- but I don't know what's causing this one. It started appearing after some pretty minor changes to an almost finished map. I changed a lever into a button and set up some monitors and cameras.
"WARNING: Cluster portals saw into cluster at (1241859 314 3)"
The bit that's strange is that the coordinates given are seemingly outside the map on the X axis - using the menu option to go to thoe coordinates makes hammer go a bit odd, zooming it right in on an area far outside of the map and making the 3d display go black (I have to completely restart hammer to get it back!). The screenshot I've linked to below shows what I'm getting.
Any suggestions?
PS This error does not stop my map working, in fact it seems to have no negative effect whatsoever - I just don't like having any compile errors
