is there way to reset what blueprints you accumulated?

i installed mod trying have more inventory stash place ,uninstalled mod the mod gave me every blueprint learned in game i odnt want start over from scratch lose 200 hours worth work. on 2 level 100 characters.

i went with item assistant manager tool,i wish i knew this before i used custom game mod i forget mod name im not happy i learned every blueprint mod didnt specify it did this, if it had done so i not installed it.

Don’t mods have their own save location and therefore their own blueprint collection (dir save/user instead of save/main) ?

If not, the only way to reset would be to delete the formulas.gst file, but then you start fresh completely, with no blueprints.
