... I encountered a bug late in the mission that's preventing further progress, and I'm not feeling up to replaying a mission I'm three hours down in. There's a great mission here that is rich and detailed from the smallest nook to the tallest room, and the surrealism really makes the mission 'pop'. It is, admittedly, a very lenghty and complicated mission though, to what will likely be the point of tedium for some. There was enough here that was keeping me engaged, and would've kept me engaged up until the end.

So as a provision for future players, don't blow up spots marked with an 'X' until you're absolutely certain you need to.
