Garry's Mod - All weapons-capable NPC's are t-posed!

Hi, I am having an issue where I spawn an NPC, both HL2 and modded (NPC’s that can use weapons), immediately spawn in the T-Pose position. I’m wondering if it has anything to do with the Gmod Update 161. Any suggestions or solutions will be really helpful, as I use them for making Gmod Movies. Thanks!

Known bug.

Since the update? It hasn’t done until after the update…

Yes, since the update, also, reads the sticky.
