This mod does not like Editor Extensions by raiguard; Went to use Editor Extensions and as it was loading the mod's lab scenario it first took way longer than normal, then went black for several minutes before finally finishing. As the Creative mod asked if I wanted to use it, I selected no. Then things started acting all janky as I tried to move but it smoothed out after a few minutes. Then I noticed that I couldn't click on anything, so I hit esc to try to quit but I couldn't actually click any buttons. Then closed that menu out of frustration and then noticed I couldn't move anymore nor could I open the esc menu. I couldn't do anything. I thought the game crashed; but all the sounds and music worked, and nothing looked frozen, I just couldn't do anything, no clicking or buttons. All I could do was a hard shut-down of my computer. No crash report was generated. So yeah, this mod and Editor Extensions apparently hate each other.
