Completed Triumphs Keep Popping Up On Screen When Using Destiny Item Manager.
There's an issue that causes Triumphs that have already been completed to pop up on your screen when you're transferring weapons and gear using the Destiny Item Manger (DIM) Google Chrome extension. I don't know if this is a known issue or not, so I'm just making a post about it just in case.
I was also told in the Destiny Item Manager Discord channel that this issue has also been reported on the Bungie GitHub page.
