Loaded out with a UMP and LR. Dropped the LR and picked up an MP5.
Now I have knife, beretta, ump, and mp5. I don't use the scrollwheel to switch weapons on my config (it's disabled). When pressing the numbers for UMP, it wont switch to UMP. I can now only switch between MP5 and beretta.

I think dropping the lr (a primary weapon) and then picking up an mp5 (a secondary) and having it go into the primary slot might be triggering this bug.

I, too, have experienced this. It's quite annoying but I have keys for every weapon so I would just hit my primary button if I wanted the UMP out.
