That happens to me to, im not to sure what it is, its nothing to do with the world its player related. the reason it crashes is, when you presss it it changes the mode of the ring to protect you from mobs and its has a forefild affect which is changing the area/chunks around you which will overflow the game leading to crash. just like if you have a lot of big machines which has alot of anmiations. Well what i think it has to do with the amount of ram you have and or alocated to your tekkit.
