As the title says, if you kill the boss (Seto) while you’re in that colorfull room, all your loot will be dropped there and you’ll be teleported out before you (or you pet) can grab it, resulting in the loss of several T3 honing materials. This is a very big issue that led me to lose my loot twice in my main (normal and hard) before I noticed what happened, just wanted to let you guys know what’s going on and how to fix/avoid this.
Same thing just happened to me. I heard and saw the loot spawn but the cutscene teleported me out so I didnt collect anything. Hopefully it gets addressed
