Rail child block invinsibility

the basic rundown of this bug is that if you make a rail move of of the activator rail and onto an extension rail and then destory the activator rail the child blocks in my case a door become completley invincible and cannot be destroyed by the player by any means(trust me i tried)

No idea if this is replicable or not

to prove my point heres 12 lasers i decieded to fire at the blocks to remove them



yup completley invincible the lasers just hang there in mid air

same with rockets and beam i forgot to add that bit

also just noticed my terrible spelling of invincibility
