pathfinding walks though solids?

Hello. in my project sometimes the path finding behavior will cause NPCs to walk though walls. but when I restart the layout it then works correctly. anyone ever have this issue?

Try rebuilding the obstacle map a few seconds after you enter the layout, do they still have the problem? Might be because obstacle map is built before the objects have fully loaded into memory but this is just a guess. I know it generates the obstacle map once only on start of layout.

sorry for the delay. I found out what was "causing" it. at the end of a round I would set the AI's object time frame to zero. but I only set it back to one a second after the new layout loaded. by setting the time frame back to one before leaving the issues seems to have corrected itself. My guess is the obstacle map did not update while the time was set to zero.
