Node issues

I’m very new to noding and AI in general, and I have laid out a load of info_nodes on my map. For some reason, the nodes in and around the lake are unlinked and I have no idea how to sort it out.
There is a trigger_hurt in the water that affects only players, could that be it?

I htink it is encoded in source that npcs are supposed to avoid sludge.
Try a regular water texture
Oh wait… zombies dont mind it lol.
Uhm. Idk.
tried removing the hurt brush?

Tried just now, no change at all. :frowning:

Bump:
Fixed by removing the bowl shape of the sludge area :frowning:

Why didn’t you just link them in-game?
