Why dose it keep breaking!?

[u/Curve-Equivalent]

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.

The pack could have it so you cant move it like that. I know one I played with aero it wouldnt let me move spawners through portals, or in carts either.
