The error occurs with a turret in the Galacticraft mod. If the turret behaves normally on the ground, then if you go into space and place the turret in airless space, then it begins to receive continuous damage. If it is in a sealed room or inside a bubble with air, no damage is done. I contacted the developer of Galacticraft, and I was told that the turret is defined as a mob, so it takes damage in space. But in that fashion there are mobs who do not care that there is no air. These are alien inhabitants.

What versions are u using of MC, Galacticraft and Technguns? I have a world loaded with turrets on all planets and they are receiving no damage.
