The issue is because of a disconnected path between two nodes on the stairs here:



To get the game to show the nodes like in the picture, type the following into the console:

Developer 2
ai_shownodes 4
ai_shownearestnode 64
ai_showpaths 2

This will give you a full view of your node system and might help you fix your issue. As for my suggestion, move the pathnode up another 8 units or move it closer to the one above.

There is also another problem. If you go to the last room the zombies which are still in room 1 try to hit me from the bottom rooms. Is there a solution to this. Please help?

it has to do with the pathing system being broken. But the zombies shouldn't spawn in room 1 anyway if you have zones.
