I'm wondering what this "APawn::TraverseFrom" function is, and in which object it causes problems. Because it reads "APawn" I expect it to come from one of the pawns I added:

auraarmy3.doppleganger
AuraGame1.BabyDevilSchool
AuraGame1.BeeSwarm
auragame1.rogueslime

I get logs like these, with all kind of monsters mentioned as 'object'.
Here the mentioned pawn is DemonFog6, but I'm sure it's not the DemonFog itself that's the problem because I'm using it without problems for a long time.

DemonFog did look different over the newest changes (blue), but I still think that means nothing. As I keep explaining to you this native unreal function FindRandomDest() is buggy and almost all scripedpawns use it (including original) except for asGard's newer creations. When a pawn happens to be in a bad spot of the map (possibly at a BSP hole) and uses FindRandomDest() it causes all of that "TraverseFrom" stuff in your log. It's trying to return a navigation point for the pawn to use for roaming around and encounters a problem. The giveaway to the bug should be what I show below about the mentioned function name and that it happened in state Roaming on the pawn.

I've had more crashes like these recently, with different pawns. The Doppleganger pawn resurrects itself as one of the available monsters in the level at the moment. Maybe that's the reason of the crash. I'll remove that one first to see what happens.

I guess that explains why the DemonFog or Manta that I saw was blue. So this Doppleganger dies and in doing so spawns another pawn with itself associated with it?

How does the BeeSwarm and RogueSlime behave? I need to play against these pawns when I have the time.

Yes, the Doppleganer resurrection were the blue pawns. I removed it.

A beeswarm is a flockpawn. It basicly behaves like a horseflyswarm, but now they sting. I use DZMapM to replace horseflyswarms with beeswarms.

A RogueSlime is also a flockpawn. It's a bloblet that goes towards players and corrodes them slowly. I use DZMapM to replace NaliRabbits with RogueSlimes.

A BabyDevilSchool is a flockpawn that replaces the BiterFishSchool. It's a school of quick and small devilfishes.

With the doppleganger removed, the server just had another crash:

I think I know why you are seeing these crashes in SkyBase now. The old DZMapM and WMutate2 are completely unable to 'monster spawn' in that level. SkyBase doesn't have its nav pathing properly built like other coop maps. To get around that map flaw I changed the DZMapM beta to use a new method which does not fail to count PathNodes in maps built like SkyBase in which are used to find spawn points.

So what you're seeing here may just be a map flaw which never had a chance to be exposed until now. It's a shame that the DZMapM PathNode counting change is turning out to cause a negative impact because in a larger scope more maps would now have support for monster spawning that didn't before.

My suggestion for now is to put any flying pawns back into WMutate2's monster spawner. It seems that only flying pawns are triggering the crash which may imply that they are flying into a BSP hole in roaming state that is not at ground level.

Oh great, this is a true relief. I never knew that WMutate2.MonsterSpawner never spawned anything here. Thank you *very* much for your support, I really appreciate it.

I'll keep the Doppleganger out of the servers becaused it might have been the cause of another crash.

Ok, I did a search for APawn::TraverseFrom in my large log archive, and found some more matches:
