Hi.
After the update, an error appeared with the mod "https://mods.factorio.com/mod/aai-loaders-stacking-filtering".
Any ideas why the update suddenly affected something in another mod?

__aai-loaders-stacking-filtering__/prototypes/stacking.lua:45: attempt to index local 'orig_tech' (a nil value)
stack traceback:
    __aai-loaders-stacking-filtering__/prototypes/stacking.lua:45: in function 'generate_tech'
    __aai-loaders-stacking-filtering__/prototypes/stacking.lua:71: in function 'make_stacking'
    __aai-loaders-stacking-filtering__/data.lua:24: in main chunk

that mod expects both a technology and an item of the same name, it is an issue with that mod and not mine, report it there please.
