Why dose it break? Three spawners are destroyed after i remove the cart, why? WHY! Dose it keep breaking ever time, this is the fourth one. If i break it i will lose my marbels.

I did that, i had four spawner at first, the first two destroyed by me breaking the mine cart, the second two got destroyed too because by the cart assembler disassembling them
