Hi there, Jeff from Irvine Ondrey Engineering here. We provided the control system update on Beast. We haven't heard anything about the current Beast closure so we don't believe it's related to the control system, which has been operating smoothly since we installed it.
There are a lot of different parts on a coaster besides controls, and we still live in a world of parts shortages and long order times post-Covid. I'm sure the park is working as fast as they can to get whatever part is needed.
