I have just contacted Storm8 but they say they can't respond to individual RS messages anymore. Hoping to find help here.

I fully built 3 Top Degree Ovens in the current Graduation goal but I placed them in storage overnight whilst I was cooking longer recipes. I went to get them back today and they've all gone! I'd have to wait for the goal parts to all be fulfilled again before cooking recipes which are already on my counters! Anyone else got this glitch, and how can it be fixed if Storm8 won't look into individual messages anymore?
