why cant i create a map everytime i try a message just pop up and say something about complication error.plz some1 help me

For me I'm not having that specific error. However, I am having this weird glitch that flips my mobs, objs, and turfs around. Then crashes dreammaker.exe. Forcing me to open dreammaker.exe again. I've done everything and yet this problem continues to exist. Perhaps it is the Byond version 3.5 Dream Maker.

I suggest that you reinstall byond.
