Underground, there's a ladder, need a dice from the slums to distract the guard to get it(edit: Actually you need to defeat the guard, it might be bugged right now to acquire it because it's in the trashcan next to him, working on fixing it right now.)
can't do that either unfortunately... once you defeat the guard, you're greeted with black screen that says now loading and an error for loading an image... this is an infinite loop in the current version as the failed image will prevent the new one from loading
blackbars.png I believe is the problem image... it happens every time you battle an NPC, be it the bear guard or the three NPC's before the warehouse content.
