I was running a mono and a couple items dropped that I wasn’t able to loot but wished I did as I was looking for specific things. Screenshot: https://i.imgur.com/4bm0uHK.jpeg
The loot filter I was using is here:
I was using this for several levels without any problem. I noticed I needed a couple certain things from loot so I added two things to the filter: RECOLOR all items with summon bone golem, and RECOLOR Rare Turquoise Ring.
This is a copy of the loot filter I used with my edits: <?xml version="1.0" encoding="utf-8"?><ItemFilter xmlns:i="http://www.w3.org/2 - Pastebin.com
“Hide all magic items” and “Hide all items” (last in the list) are checked
An important distinction is that I made these filter edits while I was in the monolith instance the bug occurred in, and the bug occurred within 2-3 minutes of the change.
Things I tried: Disable/Enable filter with X keybind, did not solve issue. I changed to No Filter, did not solve. I made a new filter, did not solve. Someone in global chat suggested ALT+Z, but this brought up my AMD video card overlay and did not solve the issue.
I had to leave the potentially great items on the floor as I left the monolith 
Other people I spoke to said they have experienced this same problem and had no solution. I hope this report can help the devs pinpoint the cause of the problem if they haven’t already (I hope they have).
Thanks
