Hi,

I'm having an issue where zombies will just straight up lose sight of me, and will stay fixed on the ramp doing the 'idk' animation.
Getting right up close to them forces them to swing and move forwards, but they never look for me again outside of being literally on top of them.
Was using a terrain patch and figured it was the angles of verts messing up, but having the same issue with a simple brush rotates to form a slope between the lower and higher ground.
Would also like to note zombies are spawning correctly, and that movement only becomes an issue on this ramp.
Turned ai_ShowNavMesh in case anyone wanted to see that.
Really stuck and don't see much point progressing until this is resolved. Any help would be appreciated, even if its a point to another post with a similar issue!

Thanks in advance.

Try to add a pathnode at the top of the slant. - CLICK TO SEE EXAMPLE PIC

To add pathnode press B to open entity browser, then click on node and then drag in a pathnode.
Try that and let me know if that fixes it. Also make sure you don't have any perks under the sland, and also make sure there is no breaks in the geo
