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
