I keep a lot of blueprints and books in my car. I just installed the mod and loaded my outpost building car on, when unloaded, all the blueprints in the car are now blank and the blueprint books are empty. Fortunately my good books are were on my person, but I'll need to re-collect my Nuclear build.

At least it didn't eat the Vehicle grid placed equipment. That would have been expensive.

Thanks for the report. I can reproduce the issue, but I won't have a timeline for a fix until I can investigate an optimal solution --
From what I remember with my other mods, copying blueprints/blueprint books can be quite computationally expensive. Perhaps a new API has been added since my last attempt that will optimize the process.

Maybe get the blueprint strings from the blueprints/books and store those?

This bug has bitten me too. Of course, in 0.17, it likely won't be much of an issue anymore.
