Trials of Strength

So after beating the boss I wanted to pick up a couple dropped items but inventory was full, so I went to town like I've been doing since the start to dropped them off or quick sell items only for the portal to still exist but not be clickable to go back to boss room and use the keys and other rewards. Though after doing it again I found the stash chest inside the treasure room. It would have been extremely helpful for at least a warning to the player that leaving to town block you from returning with maybe an *ARE YOU SURE* pop up or maybe a text warning in the chat about it.
