You may want to limit the size of the storage containers to reduce the performance hit over time. I have a preliminary report of some very severe memory usage associated with this mod. Perhaps consider using deepclone only on demand (construction or actual saving), rather than keeping a full clone of the structure, for all blueprints, in memory at all times.

(This is based on an AI analysis of the mod's codebase. Apologies if it's an inaccurate representation of what the code does.)
