Playing on 1.28 experimental Chernarus:

1. Recently spawned and found a White Mens Suit Jacket. Having found various items and stored in the jacket, when switching to a new jacket, suit jacket disappeared. This was in a small kiosk (no ladder) next to a school building in Cherno. Pressing tab did not show the dropped jacket or items, wasn't outside. Went to the roof of the school, the dropped jacket was not on the roof of the kiosk. Completey disappeared.

2. Swapped to an alternative server and spawned in Kambiwobo, Found a Green Tracksuit jacket and stored some items. Went to the Police station and swapped trousers to Police Pants. Upon leaving and pressing tab, the Jacket was missing from the inventory. The items that were in the jacket and assigned to the hot bar (knife, bandage, etc) were still on the hot bar and useable this way. I had to place the jacket in the hands of the character and then put back on for it to reshow in the inventory tab.
