I strongly suggest you to add to your blacklist.xml the following nodes:
<bad_location><name>Fel Iron Deposit</name><waypoint>-2040,19 4219,911 -3,268106</waypoint><comment>Underwater node(Terokkar Forest): 17/01/2010 17.25.44 </comment></bad_location>
<bad_location><name>Adamatite Deposit</name><waypoint>-1977,4 4222,03 -3,44394 </waypoint><comment>Underwater node(Terokkar Forest): 17/01/2010 17.26.20 </comment></bad_location>
or your pg will maybe dismount in water and never be able to mount up again!
