In short, with the latest update, NPCs from my maps no longer spawn and appear to be completely removed from the published maps. These include both fortnite characters and custom characters with Verse scripting.
Steps to Reproduce
Put a NPC Spawner device in a level, set up the necessary defintions, publish the project. The NPCs do not spawn.
I can confirm this - custom NPCs simply no longer spawn as of Fortnite+Release-29.10 and Fortnite+Release-29.00.
Verified on both PC and Xbox, published map code 6383-3623-7956, which was published prior to the latest Season (i.e., it was published during 28.x).
NPC Spawner:
NPC Behavior Script Override = None
NPC Character Definition = based on Guard, with many options modifications.
In the UEFN Editor, if you forcibly replace the NPC Behavior Script Override with something other than āNoneā, the NPC will spawn, but that forces you to hand-code everything, whereas in 28.x the SAME build allowed you to just modify Guardās defaults.
i.e., the bug appears to be that āNPC Spawner instances fail to spawn NPCs if the NPC Character Definition is custom, but the NPC Behavior Script is NOT overridden.ā
