Isn't it the cold that makes it flaky though?

Used to swear by my corner jig until it slipped on a face frame and cost me a whole afternoon too. Pipe clamps and a good square just work, and now mine sits in a drawer.

47 empty stores out of how many total though? That's the part I'd want to know before getting worked up. A lot of malls have been half empty since like 2018, way before any foreign owner showed up. The roof leak sounds bad but that's a building problem, not proof the Cayman address is the reason. Shell companies hold property all over the place and plenty of local landlords are just as slow to fix stuff. The Sears still opening every day tells me somebody is paying the bills and keeping the lights on. I'd look at the mall's tax payments first, if those are current then the owner thing might be a lot less dramatic than it sounds.
