Mining around ludicrous amounts of dark tile when you don't want to drop down. I went from the ladder to the zonewall and turned left toward a new corner on a lvl 7, and hit a gargantuan dark tile patch. I was eventually raging my ass off. I'm almost to the corner zone wall by now. Basically, got ***** out of 1/4 of the best metal on the level. At least I have 1000's of boulders to chip during the next Blood Moon.
I got tired of screenshotting it. It's a lot bigger than it looks. It's either one solid patch that is hundreds of units long and possibly also wide, or it's several smaller ones in a tight cluster. Maybe it's common for there to be a 250x??? dark tile patch on lower levels. I don't know. I ***** hope not.
