Items And Prime Parts are Disappearing From My Inventory

[FrostPhantom]

I noticed this problem when I was going to build a Saryn Prime, all I needed left to do was build the parts but when I wanted to go build the chassis it said that i didnt have the chassis.

So I decided to check my inventory to double check and it wasnt there, I then restarted the game to see whether the chassis blueprint would reappear but its gone.

I then decided to check my inventory again to see if whether I was missing some other stuff and I was.

I was missing items like Tigris Prime stock, Venka prime gauntlet, Fragor Prime handle and possibly more stuff.

Is there a method to fix this bug? pls help

I also suffered this, my Hydroid prime Blueprint vanished mid production, I supported a ticket and I advise you do so as well.
