When you reach the the 4th Map in King Guang's Fen Dungeon 3 Stars it removes you from the dungeon and places you back in world map. It leaves you with a message, "Client Error 1." and then follows with a message telling us to repatch, after repatching however, it still remains bugged.
A couple others had the same issue as well. I'm just reporting this in case it's affecting anyone else.
If you wish to access the new map but don't have it unlocked, just complete fen in 1 star not 3.
Note: Bug has been fixed~
that happened to me also, said to restart client and as i watched, no patched files lol

i thought it was my fren's problem when we join the dungeon with him being the host since my when my fren opened Grand Chase he seemed to have problems with his comp o.o
never knew this was a bug thought
