Xbox Version 18.104.22.168 Warhead not destroying environment.
I created an Earthlike world after the most recent version using the latest version of "Multiverse2".
I copied and pasted the Cerberus Wreck from Mod.io at each of the four systems, commandeered one of them, and landed it on an ice lake on one of the Earthlike planets.
When I started to build my base I dug a tunnel into a cliff face and attempted to detonate a warhead inside the mountain (the game was on experimental mode). There was a large explosion but when I returned to the tunnel the characteristic sphere space the warhead typically leaves behind was not present. In fact, there was a tiny scorched bit of rock wall that returned to normal color after a couple of minutes. After the color faded there was no sign of an explosion at all.
Hope it gets fixed. It's my favorite way to build a base.
