Just ran a chaos dungeon through matchmaking (Punika Moon Level 2 (IL 1340). After the second level, one player accessed the portal prompting the message to move on to the next level. Other three players, including the player who initiated the portal, left the dungeon. When I tried to move on to the last level alone, the game wanted two players to accept despite my being the only one in the dungeon. It was for my daily run too .
I farm chaos dungeons too so I understand why people are leaving. But why can’t people do it in solo if they are going to leave? Kinda frustrating.
