Hi, I just contacted support but wanted to leave a comment here too:
I am sorry to report that there's an issue with obsidian ore after today's maintenance.
I had spent somewhere between 800-1000 crystals (don't know the exact number due to there are some "winnings" every time I spend 99 crystals, something comes back as crystals, as parts, as new horseshoe and some as obsidian ore) in excelsior and got some new amount of parts to start new MC campaign part 1 (three times) and plenty of obsidian ore but the mayor still shows 0.
I had done some reloads & cleared cache (flash and browser) but still 0.
