FS2004: Floating Buildings at Meigs

To compare scenery between FS2002 (still my preferred version of FS) with FS2004's scenry I loaded and flew FSNavigator's Miegs Field flight plan in each version. When I started up FS2004 and selected Meigs Field I discovered something rather odd (to say the least)! Namely, there are two large factory-like buildings on the "mainland" directly east of the 36 runway threshold that are suspended in mid-air! I'm not sure if this is a bug in the default FS2004 scenery or if it occured when I installed FSGlobal 2005 into FS2004. Either way, has anyone else seen this? How can it be corrected if a patch isn't available to fix the problem?Scott Miller
