Hey toecutter,
Could you please ask the devs to fix equipment stacking.
When putting equipment of the same type (for example MLK-III's, Basic Engines, BUFF-100s) in a planet warehouse the equipment stacks correctly. But when unmounting and/or moving equipment between ships they tend to not stack and take up a cargo slot each (while getting them from a planet's warehouse keeps them stacked).
Regards,
