We believe we have found the cause of what happened to you & implemented a fix on the development branch - unfortunately we are not sure this fix can make it into the final SU1 build but I’ll keep you posted on this (if not, we’ll have to trigger an alert both here and through the DevMode to warn users).
We would still be interested in a test package that can be used to trigger the issue in order to make sure that this fix is 100% reliable. Please see 3) Provide Private Content to see how it could be sent to us.
Best regards,
Eric / Asobo
