Bugfix: Parallel ServerOcclusion - serialization now happens only on main thread - main thread doesn't try to process lost pairs and already-serialized found pairs tasks anymore - serializing work is longest Previously serialization was offloaded to worker threads, but after investigation discovered that it would kaboom due to accessing scripting API. So instead, we offload to worker threads only players + entities that we can guarantee won't trigger serialization. Tests: 2p session on craggy with UsePlayerUpdateJobs 0, 1, 2 - ran around, switched weapons, disconnected
