Inventory Disappearing Bug

A few people on the private server I’m playing on are experiencing a bug where items in their inventory disappear when over encumbered with max encumbrance builds. From what they told me they do not respec often if at all, and it seems to happen mostly when they go over their encumbrance limit. The first 4 rows of items in their inventory will still show up, but everything after that will be blacked out and unable to move it around. Occasionally ALL items in their inventory will disappear as such.
