Map Device Lock

I was running a T9 map on a Powerful Boss node, and everything was going smoothly until the boss used a teleportation skill and completely disappeared from the arena. Unfortunately, after that, I encountered a major issue where I couldn't leave the arena. I attempted to return to the main menu to spawn into town, but now the map device is locked, and I am unable to continue mapping.

NVM the Map device sorted itself out However IS there anything that can be done about the map that Failed due to the Map Boss Bugging out
