Bugfix: FullServerDemo - use save for disk instead of network when snapshotting transient entities - Also couple safety checks for BasePlayer.Save, since now I'm triggering a path that usually isn't triggered for a class of entities (NPCs) Tests: while recording a server demo, on a procgen map in a local server did all basic activities (looting, harvesting, crafting and building) + drove a bike and attacked a ScientistNPC at outpost. Then was able to play back both demo chunks. Tests: on local standalone server and procgen world, went to pier monument and descended to find aggressive NPCs - no more exceptions in server log
