How many trash slots does each upgrade add?

Each level adds 10 character logistic trash slots, which is one default GUI row. Completing all 17 levels raises the vanilla capacity from 30 to 200.

Why is military science not required?

Personal logistics is not part of the military research path. The upgrades follow the normal progression from logistic robotics through production, utility, and space science.

Does this require Space Age?

No. The mod works with the base game. Space Age can be enabled or disabled.

Does this work in existing saves?

Yes. Enable the mod, load the save, and research the new technologies after logistic robotics.

How does this work in multiplayer?

The researched capacity is force-wide, matching Factorio's native technology behavior. Players on the same force share the unlocked trash-slot capacity.

Is it compatible with other trash-slot mods?

The technology effect is additive. Other mods that grant character logistic trash slots can add their bonuses alongside this mod.
