Whenever I create a object or build an object, but wear it after completion (Not picking it up in the inventory, but after finishing it on the ground I use the pie menu to wear the object) and relog, the item disappears completely from my inventory. To replicate this bug you must Set a item down in a build area that is NEWLY built (or you can set something from your inventory down and link two objects/unlink, ect Immediately after finished linking/unlinking/retexturing/building onto your item, wear it instead of picking it up. Log out. When I log back in the item will still be attached (about 50% of the time), but sometimes I log in and the item is completely gone off of me. And if the item stays on me, and I detach it, it will simply disappear.
