Did 15.13 break this mod? Getting an error on startup now.

Me too, I check why

TO fix this, open the mod archive, in prototypes/entity/assembly-lines.lua
At the end, near data.raw.inserter, (L 640 and L646) remplace fast by factory:
data.raw.inserter["factory-inserter-leftside"] = ins_l
data.raw.inserter["factory-inserter-rightside"] = ins_r

Fix is good, thank you Zehir!

(still waiting to build my first one!)

With this fix you can play with this mod. There is a fiew bugs but still playable

How can I make my computer able to open the lua files? because when I try to open it it askes me to choose an app to open it and I don't know what kind of app it needs
Thanks =)

Any text editor will do (Notepad++ is pretty nice.
