Hi guys,so I didn't play the game in a while and I have a problem:

My inventory is full and I tried to destroy and give the items to other players,but it still shows me 30/30.

How can I get rid of the items,do I need to necessarily buy the blueprint?

I maby could be a Glitch! Why don't you try and sell them in the Trades? Then they should be gone from your inventory, as long as they're up and you'll have some more space to get Items!

But getting the Blueprint still isn't that bad of an Idea, since you don't need to Sell Items or something all the time! And lvl 2 Bluebpints aren't that expancife usually!
