Dear Forum,
Does someone here know anything about the following Warning message?
I get it when I click AI > generate all navigation. I have had this before and deleting Rocks or Assets seemed to have helped but I never found out what exactly caused the problem.
Any help in pinpointing the issue is much appreciated. Thank you. this is what it looks like in the sandbox:

@lavizh - you are helpful and knowledgeable, any idea where I could look for this?

Something at those coordinates is probably blocking it i would guess. Whats at those coordinates?

they are coordinates? for "goto" I thought I need 3 values z x and y ... would these be x and y then? ...
... entering them as coordinates x and y puts me far away from the map in water and going down or up the z axis shows nothing - nothing there.

oohh, so simple - thank you lavizh
