Did you watch the first replay? At no point did you had a lock on the transport that dropped the siege tanks at the top. I'm referring to this moment at 19:30:
In fact, because you were stalling power for five minutes or so you didn't even have a radar blip on it. You destroyed the transport after it dropped.
Anyhow; what I'm trying to say is: please add time stamps with screenshots. I'm not saying you're wrong, but it is just too vague to investigate at the moment
