even leaving space between generals sometimes failed.
I lost 76AM recently because of this, i sent 3 generals, letting about 3 or 4 seconds between each one, the 3rd general started attack before the 2nd.
All of times i send in this order letting a few seconds works, but in last 2 weeks it seems something changes, something wrong start to happen.
Even if block is not supported, this is an issue, a bug need to be solved, because it is not related to block thing directly.
