From Giloushaker:

if its being used as a local/github system fine, but having multiple "official" nr systems with the same id will definitely cause issues, not sure if catalogues with same id in different systems would cause issues

Doing the catalogues as well just in case it causes issues for battlescribe (not that we are necessarily focusing on bs compatibility).
