Can you add an option to turn off the equipment restrictions? I was playing with mods and I could not equip some of the added pieces of weapons and equipment.

Could you tell me which mods and which pieces in particular?

I noticed it with Krastorio but didn't do any testing with other mods.

I think it is if the equipment is a modified version of a vanilla piece vs a new/extended piece.

Some stuff that works (portable fusion reactor, shield mk1/2, personal sniper laser defense mk1)

Some stuff that does not work (small portable generator, shield mk3/4, personal sniper laser mk3-4, personal submachine laser mk1-4)

I did a test with the spidertron_mk3, went into prototypes/spidertron_mk3/equipment_grid and changed equipment_categories = {"armor"} to equipment_categories = { "armor", "universal-equipment", "robot-interaction-equipment" } and I was able to equip a few test pieces (that were un equipable before) and they worked.

I can confirm, most of the vehicle equipment from Krastorio 2 does not seem to be compatible, was hoping for a fix.

Also add "vehicle-motor" If you want to use electric engines

I've added this mod here that adds more compatibility with Krastorio 2. If something is missing feel free to open an issue there, happy to add more :)

I still had issue in Krastorio2 that I could not put equipment intended for spidertron into spidertrons of this mod. I have made this mod compatible with any mod that changes equipment categories for spidertron in https://mods.factorio.com/mod/spidertrontiers-community-updates
