Portal breaks??

[SkullCruncher]

Hello, would someone know why does my map get the portals error? There isn't anything specific that I did in the map, simply normal mapping as usual and doesn't happen on other maps. It's a problem because it drains FPS so badly and the error prevents my portals from dividing the map rooms.

 

************ ERROR ************

LoadPortals: couldn't read D:\Program Files\Steam\steamapps\common\Jedi Academy\GameData\base\maps\project1.prt

 

I googled it but found no help about it.
