This version 0.3.1 is more stable and can now be safely used in survival saves. JanuHi Everyone, I have now done a major update of the mod for Factorio version 0.16.x. Please keep the bug reports coming so I can get everything fixed up soon. Sorry for this mistake, it was very late when I finished getting the mod updated. The Equipment module doesn't have a migrations folder so create one outside of the mod folder and place it in the same place as the one in the transport module. To make these work just open the corisponding mod in your mods folder and drop these into the migrations folder. This link is for the transport migration and this link is for the equipment migration.
I am sorry about that I forgot to add the new migration files. JanuI have read some of your bug reports and the biggest one I got was about the old items not updating to the new items.
