1: Inability to look through rangefinder, scope in hand, or binoculars.
Every time I try to look into a scope or related item, the animation of bringing the scope to my eye starts, the view starts to change to looking through the lens, and then it all cancels and I am left looking at the back of the item i.e. rangefinder up in my hands, as if I'm about to look through it. This has proved to be an issue a handful of times trying to get a beat on other players in the distance, and it seems to be a bit of an issue. If i remember right, the last time I was able to look through a scope in my hands was the update right after ver, .63.

2. Difficulty equipping armbands: My newest group of friends were all traveling together, and in the interest of recognizing each other in any pvp engagement, we decided to wear same colored armbands cut from raincoats. However, when we tried to equip a single piece from the stack, it would not equip. The next step we took was to split one piece from the stack of armbands, drop the bulk (I had four green armbands in a stack, when i split it in my hands, one fell on the ground, so i switched the stack with the one armband) and take the armband into my hands; however, I still could not equip it, and neither could my party. when we dropped the single armband, we could equip it at a 1:3 success rate, one time out of three tries could equip the armband via the vicinity window.
3. Opening various food/gardening items: These glitches have occurred for a number of food items, although I have found workarounds for one of them, some of them I could not and proved to be quite an inconvenience. When trying to move canned tuna from my inventory to my hands, I first thought they didn't peel open anymore and they required a can opener. when trying to use a can opener, it could not combine with the canned tuna, and no action or prompt to open it showed up holding it in my hands. When I dropped the can of tuna to the ground and picked it back up to my hands, I still couldn't open it. However, when i dropped the canned tuna and dragged it from the vicinity window to my hands, I was able to open it. Another thing I have had issues opening are seeds. Holding a packet of tomato seeds in my hand and trying use the unpack action, the animation plays through, everything seems to work fine, and when the action is finished, I am still holding packed tomato seeds instead of tomato seeds. I tried this action dozens of times, and every time I still had packed tomato seeds in my hand. Having members of my party try didn't work either, the same glitch happened to them as well. although two days ago I was able to open packed tomato seeds just fine, so this could be an isolated incident
