I'm glad that S8 could resolve this issue for you.
Hmm, I'll have to ask S8 for advice about the missing ovens and come back to you.
So, just so I understand the issue correctly, you have 2 accounts. On game 1=ID#1 back in 2014 you purchased 2 valentine ovens. Now you have a second account=ID#2 and when you switched back to ID#1 game those ovens are missing. Is that right?
