@Crafted_Powder(View Post) when coal is created it gets tmp=50 and life=110, on the other hand, when bmlt is created, it gets 0 in both of those properties. when you use that command, you only set the type of bmtl to coal, without tmp being set to 50, which is why it instantly turns into bcol, and without life being set to 110, which is why it instantly catches fire
