As shared in bugs -

The fix for the earlier training issue will be rolled out again shortly. This will again only impact player quality gained from this period during which the issue was occurring. Any quality gained following the patch being pushed has not been affected.

We are aware of the other elements presented by this issue, and will follow-up with more details soon.

I'm very sorry that this has been this hectic of a day and for all of the inconvenience caused. Certainly not how we look to kick off a new season. Despite all of this, I appreciate all of the quick reporting and details shared as it really helps us troubleshoot during important moments.

Update: Deployment has just successfully finished.
