Spoiler for Higurashi:

For the Higurashi-Umineko connection, I always assumed that Higurashi was a game created by Lambda, and Aurora created Bern so that she could watch it. It's also possible that Lambda was a piece created by a witch who is representative of Tokyo, and the real battle was between this witch and Aurora.

And, I also assumed Bern's logic error was something like saying "Rika lives past July" in red. Bern would have had to come up with a plausible way for Rika to escape. So one could say that the Higurashi series, rather then being a game like Umineko, was actually the logic error Bern was stuck in.
