Navigation menu disappears when I load the store…I have to restart the game

You got there from a Warning Pop-up about close to exceeding a treasure limit (Glory, etc).
Takes you to the prior version of Store.

(*edit. Oh, this is the new Store. Ok, they got rid of Old Store version, but didn’t fix the bug about no Game Menu still, when Treasury Limit popup takes you directly to Store)

Just restart.
