Strange asteroid deformation

So i have over 300 hours ingame of which i spent most playing Lone survivor scenario on default setings . I stayed on the starting asteroid for most of that building and learning how to play. I only went around the space to mine resources and hunt AI ships. Never had much issues apart from ice growing over one of my doors one time.

So i found this large asteroid close by and decided to build a large shipyard there and relocate eventualy, since the starting asteroid got too small for my building needs.

By now i have spent some 10-20 hours on the new asteroid building a grinder pit and a system of refineries/assemblers ans whatever.

The strange thingh is that the asteroid started out as a smooth surface with normal asteroid shapes and features and despite beeing 1 km in lenght i could only find a few ore locations.

But now every time i log out or in the surface seems to change. There are strange spherical shapes growing on the asteroid that look like tumors.

They have a small speck of ore in the center and a spherical shaped stone formation around. They also all seem to be facing in the same direction.

They appear in the parts which i have excavated, they grow over my blocks and its generaly extremly annoying.

For now i am "curing" theese tumors with mining and explosives, but its geting unplayable.

I need a fast and straight answer on how to fix it before i spend any more time on this project.

One thingh is i did notice they started to appear in larger numbers after i first time used the alt or cntrl +f10 menu to clean up debris and floating objects, i always assumed that destroyed ai ships get deleted automaticaly, but i was wrong. I found parts of ships floating around even 3000km away lol.

So....thank you all and help me.
