Buyer beware of the MD5 bug and hours lost...

The game is very good until you get the dreaded MD5 bug. This bug will erase some or all of the work you have accomplished throughout countless hours of work. It resets the affected area back to original textures and erases anything you have placed in that area, including bases, buildings, equipment or storage. This bug is always precluded by a crash to the main menu. They are working on the bug and state that the bug is decreasing in appearance, but I would recommend staying away from this game until they fully have removed it due to the difficulty in starting anew each time it happens. Otherwise, I enjoy the game.
