Perhaps in this specific case, the violation is irreversible, but in my opinion, this is not a reason to nitpick every time and refer to the rules regardless of common sense. If we follow R55Max's logic, then Tvarine should also be given a technical loss against Amil for the fact that in one of the scenarios, he took a secondary town away from Vidomina with the help of a Necromancer expert, which is utter nonsense.
Therefore, online, it is necessary to compensate for this with strict punishment - an immediate technical loss, regardless of the circumstances (whether it had an impact or not). Simply to avoid unwarranted expectations.
This is one of those cases where the law is harsh, but it is the law. And when the simplicity of the rules and their educational value are more important than their fairness.
In my opinion, that's the case.
