before the release of the DLCs and when the game was not free to play, i was able to enter and play any dungeon, but now, i can only enter the dungeons that i complete before the DLCs release, and every time i try to enter a dungeon that i didn't finish or never entered before, the game closes and send me to a crash screen.

is there anyone still able to enter those dungeons even without the DLCs? should i buy the DLCs to play the old dungeons that i still didn't complete?
