If that were the case, it would mean the Kraang themselves wouldn't be able to rely on their own portals to synchronize their work, such as during The Invasion, Part 1.

Also, noticed another plot hole in Beyond The Known Universe: Honeycutt said they couldn't go back in time six months a second time if they were to fail, because the black hole sucks time. But that's not how it works with black holes. All gravity wells cause time to slow down by a certain degree, including the Earth's own gravity well. And at a black hole's event horizon, which is the strongest gravity well, time stops completely. But implying a black hole could suck time in the past before its creation, and furthermore make time travel impossible even light years away from it, is a huge plot hole.
