Hiya! I've noticed a few people alongside myself have been having issues getting Bendy's new NPC and PM to show up, and after tinkering with it for a while, I've found a fix.

Now, if simply unsubbing and resubbing doesn't help, one other thing you can do is go into you're addon folder which is located here:

D:\YOURNAME\Documents\steam\steamapps\common\GarrysMod\garrysmod\addons

And from within the Addons folder, you can either manually look for or use the search bar and type in Bendy to find the file named:
bendy_and_the_ink_machine_v1.4.0.4_-_bendy_(ragdoll__pm__npc)_1378770908.gma

(Note: The number and location might vary for you.) I for some reason had 2 of those, one being the new one, and the other being the Ragdoll only version. From there, I deleted the Ragdoll only version and unsubbed from the current version. After resubbing, I started my game, and bam! Bendy finally showed up. I hope this helps some of you having issues! I created this to help some people and simply link them to it. (And so I could stop pestering jQueary.)
