OMG my Gold league Perfect team was replaced with a Silver tournament roster
 

I'm reporting it here in addition to the support e-mail in case it happened to anyone else. My entire starting G303 team was deactivated and replaced with a Silver tournament team. They are all on reserve for 14 days! I'm in the midst of an 11 game winning streak so this is a giant, giant bummer.

edit - Win streak over as my completely overmatched team just lost. :( That's okay. Mistakes happen and bugs are bugs. No software is perfect.
