Vanilla rockets sometimes pass through 3+ layers of small grid armor before exploding
This was brought up by reddit user edenlovegarch and verified by piratep2r.
Problem: randomly but frequently, vanilla rockets will magically pass through at least 3 layers of small grid armor before exploding. This means the explosion happens inside the target! Note, they are not drilling a hole, they are just magically exploding inside the target.
Due to this bug, one rocket hit can destroy even the most heavily armored small grid.
