We are currently in the process of rolling out a hotfix that will disable the animations for Galakrond. The reason for this:
We’ve found multiple occurrences in which Galakrond’s animations can cause the Hearthstone client to disconnect. The primary occurrence: when playing Quest Galakrond Shaman, we encountered (as well as received word) a bug where the client would disconnect after using Heart of Vir’naal + minions with the Invoke keyword.
This is just a temporary solution that will fix the client disconnects . We are aiming to ship a client patch within the next week that will be the long-term fix for this issue.
The team is continuing to keep an eye out for issues, so please do let us know if you encounter more pesky bugs
