Sudden crashing going into design/inventory mode

I've been grinding like mad all day so only just stopped to to see what pieces I've earned. And I don't know as I have this problem too. It's been a bit frustrating as I've been waiting for bottles all yesterday and today to earn blueprints and am still not sure whether I'll reach 70,000.

The glitches are really getting me down. The crashing & freezing when visiting has been a pain.

My husband also cannot access his inventory. (Although he has got to the end. Lucky man!)
