Is anyone have similiar problem with chuck shield's blueprints?

[wolkenwand]

I have some glitch in chuck’s shield blueprint, he always have 4 shield where two of it is never updated, meanwhile the other bird is always have 2 and will get replaced if better shield type appear. this two bugged blueprint of chuck ( a scroll and a skull orb that i will never craft because it is too weak ) is cluttering my anvil screen. does anyone have similiar problem? or its only in my save game?
Here is the screenshot:

I think I read somewhere in the forums someone else experienced this. I also notice it in my list of blueprints. This should probably be moved to the bug thread.

My blueprints screen is similar to yours with Chuck having 4 and the rest having 2. I always thought I had acquired more blueprints and wondered what happened to them, but it didn’t matter to me since every item I use is either a pig or set item.

Thanks for for the information, its not only happen in my save game then, but also everyone else. i think the bug is in scroll and skull blueprint, the game read those two item type differently than other chuck item so it remain in there although better item appeared.
