Is this mod compatible with Space Age / Krastorio 2 / Krastorio 2 Spaced Out?

It worked with Krastorio2 - with its modification of car grids, with its new tank, with all its unique gun bullets ammo. With version 1.4.56 I tested it myself. Can't say for newer versions.
Concerning Space Age - should work with different surfaces without problems. Quality mod is ignored for now, maybe will add support later if there will be requests for it.

using this with k2SO, mod not working, turrets never loaded in default t1 tank (not advanced)

Probably Spaced Out replaces vanilla equipment categories. Only K2 and BobVehicleEquipment custom equipment grid categories are supported.
Will take a look.

try the fix pls.

try the fix pls.
