hey, currently in our game we have a system that raycasts downwards multiple times per second to detect what room you’re in. this raycast checks for a specific CollisionGroup.
(insane visual)
about 4 hours from this post we started getting numerous bug reports that all related to this system. we haven’t updated the live game in a while and it has been working fine until now, so my suspicion is some Roblox engine update.
it seems like after a minute or so the raycasts stop detecting any new parts made from there on. duplicating the base parts and moving them around numerous times eventually might make the raycasts start working again but is not consistent and i only got it to work once. changing the raycast to detect anything with no whitelist/blacklist, and/or changing its position and direction has no consistent results (sometimes works, sometimes doesn’t) either.
ultimately i could not find a workaround; the game is still bugged until this can be fixed.
