Weapon disappeared when interacting with omnitool object while looting with full inventory.

[AhhhMyBucket]

I was looting a mosquito beak while having a full inventory and pressed E while hovered over a blade of grass. I took out the omnitool, unequipping my weaver daggers and placing the beak in my inventory. The daggers are not on the ground nor in my inventory. I had this issue occur last night with the same scenario, spamming e to loot and hovered over a grub, lost those daggers too from taking out the shovel and looting a grass fiber.

Guessing when the game sees your inventory full and you take out the omnitool, your weapon is held in an extra inventory space. Having the tool out equips that specific omnitool to your strong hand, while your weapon is not deposited into your inventory. Perhaps also having the torch auto-equip with the omnitool since it is not equipped with the dual daggers is causing an issue with the opening inventory space on omnitool use.

Anyone else experienced this?

I get this as well, had a larvalance disappear while fighting too close to a blade of grass.  Creature dies, I go to loot, blade of grass comes over, I pull out Omni-tool and lance is gone.  But I've had this happen with only half an inventory so it's not due to inventory space.

Prior to yesterday's update, my main weapon also disappeared and not sure what happened.  It was not thrown or anything.  I was using the Red Ant Club then a moment later I noticed the Bind icon was transparent and the weapon disappeared.

YES! Glad to see I'm not the only one. Yesterday I lost my Wolf Stringer and at first I wondered what could've happened, since I occasionally had lost a weapon before by accidentally throwing it away. Except normally I'd either find it back pretty easy with the little icon that pops up or if I didn't find it again right away I'd probably come across it some other day by coincidence. Except yesterday I couldn't have thrown it since you can't throw the bow's. So after searching for about half an hour and removing all grass and other thing from the surrounding area I finally gave up. 

Today however, I was pretty much in the same area and I shot 2 aphid's with the unique staff Heatwave (since I didn't have my bow anymore). Upon looting I also pulled out my omnitool since I stood right next to a peace of grass. When I tried to back-up to adjust my position a little bit the omnitool got stuck in a loop and kept swinging at the grass even though I already backed up  out of reach of the grass. Now I tried to equip the staff again, except the image in the circle was grayed out and when I checked my inventory it was gone. I was scratching my head and looked around again, cursing myself for throwing away another weapon (see staffs can be thrown). Since it was a unique weapon I am unable to craft another one, so I kept searching for over 3 in game days and nights and was determined to find it, but to no avail. After the 3rd day I finally gave up, marked the spot with a burial trail marker to never forget where I lost it. 

Then I went here and to my surprise i saw your post. Yes this is what has to have happened to me to, because I was surprised that I couldn't find it anywhere, since it just happened. I guessed maybe it fell through the floor or something, but your description makes way more sense. Thanks for sharing and hopefully they fix this soon. 

Thanks again!

Ps. Does anyone know if there is any way the devs would be able to return the weapon to me? Since it is a unique one and I can't craft it again in this save.
