I wanted to build a little quality setup but I just figured out that a normal electric furnace has 2 Module slots but the micro furnace has none.

Ill check what's happening

It would be nice.

@Wip-Sama as an idea because there is a new belt tier. Is it possible to get another tier equivalent of the new turbo belts or is there a mod setting for it?

Ill add that tier to the vanilla one, in the next release, But I don't remember if that tier of belt is vanilla or space age.

It's a different implementation in those 2 cases.

The new belt is from space age but maybe make it so that it is available when you have the mod space age active?

It seems this is due to the API changes in version 2.0. After my simple testing, the slot issue can be fixed by making the following modification:
Change module_specification = {module_slots = tier.module_slots, module_info_icon_shift = {0, 0.8}} to module_slots = tier.module_slots in lib\entities.lua

ill add this today if I can
