It could be a bug, but it is not insane. If business A makes a deal with business B and B is in a country that gets in a war and is not able to deliver, A will have to sue. Company A may be understanding, but they have a contract and a duty to stock holders.
In fact B may not be in a war, but some of the material needed comes from a country that is in one, same thing.
