Hello,
I tried it with several nukes. It happened with all long range rocket nukes of 20T upwards. It happened with the shotgun ammo. Also with the 20T artillery shell, and everyhting larger. (I would say probably everything but i didnt test the MG ammo or grenades).
Just to emphasize, i could disable the huge fireball deleting resources in the huge area of impact of the nukes. I could not disable resources getting destroyedby the black crater though. (To my understanding i have to later mine/deconstruct the wall of the crater and landfill it)
Like the one post 1 year ago with the same issue, i wanted to start a big base with max enemies (never played wih such mods and have never gotten into ultralategame) and thought lots of nukes (i like your nukes) would be a really nice way to remove the biters and the enriching and tritium seem like a fun challenge aswell.
It can of course be, that thr mistake lies with me,but your checkbox to leave resources unharmed did not work for me.
I will try it again in 8 hours, reinstalling the mod etc, running it on vanilla.
