Since 1.27 I'm getting reports of pristine, *pinned* grenades exploding on players while moving them within the inventory, like from a backpack into trousers or anything else.
I tried to reproduce it, but was not able to do - but I figured out that you can put an unpinned grenade into a backpack with grenades, but the other grenades in there did not change its health, the backpack slowly got bad, the attached hatchet stays also fine. I would assume that they would explode in the same way as they do when you put them outside of the backpack.
