when trying to load both mods this error pops up, i assume because one of the machines is called "laser assembler"

Failed to load mods: Pacifist/functions/recipes.lua:188: Didn't handle ingredient laser-turret(item) of recipe fu_laser_recipe
stack traceback:

Thanks for the report, I'll have a look

Fixed with 2.2.16 - there remains an oddity that the laser turret is named laser asteroid defense due to my space-age adaptations, but that's only the name and will be remedied with an upcoming localization rework.
