Ive never had anything but component BPs drop from crafting components, and as far as I know nothing else should drop. Maybe you should send a support case to MA and ask if thats a feature or a bug?

Why would you want to screw up a good thing? Dont send a support case, just hope you get some high level attachment bps along the way.

Because if it’s a bug, using it to your own advantage would be an exploit.
AFAIK ppl simply reported the “longblades-don’t-decay-when-attacking-other-players-in-non-pvp-but-give-skills”-bug and happily chopped away under the “assumption” that it was a feature as long as MindArk didn’t fix it.
Do the same with this feature/bug: report it to ease your concience and keep clicking. In any case it shouldn’t prevent you from crafting basic filters as it’s a pure bi-product of your main activity - namely crafting filters.
