Character already equipped with both Jeans and Backpack with items in inventories. Picked up a IJ70 which auto placed in backpack. Went to look at the gun and that's when I noticed that I was not able to access the backpack or jeans. I was able to put the item in my hands or drop and that allowed me to access their inventories, but when reequipped they were inaccessible again. Logging out and back in again allows them to be accessed once again while equipped.
This has happened multiple times starting yesterday 3/22/19.
