It seems the Grumio's Trick Bag bug was fixed for me and I hadn't realized it. The grenade shells were stacking in the bag. The bags and containers are still flipping out for me on both the toolbar and the inventory.

EDIT : I'll post a screenshot to see if I can help you guys identify the problem.

Here's a video of selecting the items in the bag aswell.

(Couldn't figure out how to post just like the video. Sorry!)
