Walkthroughs for custom maps.

Marmot, thanks for the info. I wrote directly to the map creator, and he replied! I didn't even think he would, but he did. We're currently exchanging messages; I'm trying to explain my problem in broken English. He immediately said that he hasn't played in a long time, and the map seems to be from 2009. I sent him a screenshot of the place where the game gets stuck. He said he'll take a look and try to remember what he did there, saying that he "made a real mess" and doesn't remember how or why. We'll see; I'll update you on the results.
