As stated last night, we were not aware of this disability being added in the patch. At this time, we're not sure if it was intentional or not and are awaiting a response from the developers - however, they are currently on holiday leave for the Chinese New Year. When they return and when we have a response, it will be announced to the community.
Until that time, we ask for your patience and understanding and to not make multiple threads about the same issue.
Thanks.
