Is there a reason they beefed up security again? There was no one and no alarms when I visited this place!
I haven't heard any reasons but the last time I was turfed out the guy said that there was a high risk of falling through to the basement no matter where you walked around on the ground floor... I also know they were "going to start renovating" which I'm not sure was true but it probably meant an influx of explorers and they got sick of having to kick out so many people maybe?
