Licensee has reported a couple cases of an assert happening stemming from FRecastTileGenerator::AddReferencedObjects in a built game. They are limiting the MaxTileGeneratorTasks to 1. The crash occurred in game while there were 2 navmeshes (big agent and normal agent). They noticed that the tile generation task had finished in its own thread at the same time that the garbage collector ran its TFastReferenceCollector task that reset the array which was being looped through.
They have seen this one other time, but they do not have a any firm steps to be able to reproduce the issue.
