When I finding random dungeon with my friend, after teleport inside, it is writes "You are not in your group's instance" and after small timer drop me and my friend back. It doesnt exist if someone finding it solo. Explain please, is it bug or am I doing something wrong? It happens every single time.

Someone advised me to teleport to someone in dungeon, but if I tp back to dungeon it doesnt give me uncestors supplies and bonus exp. I mean this dungeon doesnt consider finished as random dungeon.
