That's interesting. There wasn't staff there before. It was just cordoned off by rope. There was only staff there for about a week before. If you go round again, can you mention to them that it tested on Saturday and see what they say about it...
I agree that they might be doing some final checks before they start testing fully. I know it's a bit different but they also stated at the time that Hyperia would only be testing on weekdays when it first started testing, so that may be something to keep in mind too.
