Describe your issue.

using (idk which mod but it's a mod) I right-clicked on a shulker box (in my inventory) to put items in it, (the shulker still had one place left I think), it put the items in (the mod is done for that, so it's normal), and after, I put the shulker on the floor to pick up another item, and I lost nearly all my items, the shulker was nearly empty, before that the shulker was nearly full, but it was now empty
