So I had a few different loot filters and today when I tried to play I noticed nothing was being filtered so I went to check and none of my filters were there anymore. After trying to add a new filter it wouldn’t let me, I tried to close the filter screen to ask chat and I was unable to close the screen.
I rebooted the game and tried again, same thing, no filters and screen was stuck/bugged.
I am not sure what caused this bug but I fixed it by going to:
\Users\YourUserName\AppData\LocalLow\Eleventh Hour Games\Last Epoch\Filters
and deleting ALL my filters and when I booted back into the game I was able to add my filters back and close the screen. I am not sure what caused this to bug out but this is my fix for it if anyone else is having the same issue
