Missile Silo monument floating gap above

"Hi Shemov, I’m a huge fan of the Lost Horizons map! I’ve been running it on my server and noticed a small issue with version 1.9b: the is spawning slightly above the terrain level, causing a floating gap underneath it. I've already tried clearing the server cache/save files to see if it was a generation glitch, but it persists. Just wanted to bring it to your attention in case you plan on an update for the map. Keep up the great work!"
