Q: Why?!?
A: Factorio uses two different systems to cope with blueprints.
LuaRecords are used by the blueprint library and have sever scripting limitations.
LuaItemCommons are used everywhere else and have vastly superior scripting support.
but LuaRecords can retain data from unavailable mods. a feature crucial to syncing across different saves/servers.

my sorting mod can almost do nothing with LuaRecords, so i am forced to keep a blueprint book in my inventory for fully automated sorting.
but i wanted to have a convenient way to sync my blueprints across different saves, thus this mod was born.

Q: I got the message that your mod is malfunctioning. What does that mean?
A: Instead of halting the game my mod tries to "gracefully" ignore errors. If this happens only once and you have no idea why, you can probably ignore that. But i would be happy if you filed a bug report regardless.
If that message is a regular occurrence you should definitely write a bug report, because you or a mod you use does something i have not accounted for. or i forgot something.

Q: Fine, i'll write you a bug report. What do you need?
A: A description of the error, preferably with exact steps to reproduce, be as detailed as possible please.
