Just did some Shadowlands transmog runs in Castle Nathria and Sanctum of Domination. I was getting all of the excess loot from Nathria just fine but once I got the tail end of Sanctum where there’s no vendors, I just did my usual and looted the bodies though my inventory was full. Got back to a mailbox in Oribos and only received mail that was greys I had skipped earlier in the raid.
