b Error placing modules with 2.1.x

There was recently an API change for a function called ItemPrototype:fuel_category -> ItemPrototype:fuel_categories. An error to this effect appears whenever a building in range has module ghosts.

Message:

LuaItemPrototype doesn't contain key fuel_category

Just naively, I made this patch and tried it. No more issues.

Thanks for reporting this and testing the replacement!

I checked both maintained branches. Your change fixes this error on Factorio 2.1.20 and newer. The code only checks whether the item is a fuel, so no further changes to the fuel insertion logic were needed.

The fix is now available in Nanobots3 5.9.3, with compatibility preserved for earlier Factorio 2.1 versions that still use fuel_category.

The Factorio 2.0 branch keeps fuel_category, since the API change only applies to Factorio 2.1.20 and newer.

Thanks again for catching this!
