Note: the map 08 version in cngst192_old_map08.wad was recreated based on a video of the old map being played (https://www.youtube.com/watch?v=rGGT1yR4_9Q). The only required changes were moving the stuck imp to the lift behind it at the start, and using the correct node builder on saving (glBSP).

Note 2: the date of this WAD (2017_07_22) is taken from the time of the posting of the original thread for Congestion 192 in the iddqd.ru forums: https://i.iddqd.ru/viewtopic.php?t=1328.
