Alright, I didn't read everything but when you try to put a trashpick on your back, it often slips on your back and then immediately goes back to your "trashpicking" position.. I know this is probably the worst explanation ever but it's a glitch as far as I know.
Doll glitch/bug, has been mentioned in other threads but still isn't fixed- when you tap the doll in your inventory, it sometimes doesn't give you the option to select something and then it the first page of dolls will be displayed on your screen in the overworld.
PBP glitch/bug- when someone has died, and you shoot them at the right moment with your pbp, you'll be able to damage them without them even being on their feet, they're still respawning. Pretty unfair, as you can do 40 damage while your enemy isn't even capable of doing anything...
Morano glitch/bug- when you equip a morano and you had another gun equipped at first, it won't shoot until you retapped the shooting button (so not the violin case), also a little annoying because if you switch weapons in the heat of the moment and then that happens, chances are you'll die without being able to shoot back.
I'm not sure if this is a glitch or if it's intended, but apparantly if you place a trap and keep shooting it it disappears after 15 shots or so.
