Lost loot not working after getting to 300 bank slots

I have a Zane character going and just now hit level 53 and purchased all 300 bank slots. This is going on during the broken hearts event. I then switched in the title screen to coopetition played for 1 hour, then switched back to cooperation. But now, nothing shows up in lost loot, even though I know I leave all kinds of stuff on the ground. Anything I can do?

Try restarting your game completely. Stuff doesn’t go into LLM duing coopetition mode, so either nothing blue or higher had dropped after switching back to cooperation, of the change didn’t register into your session.
