An update to my post...if I disable ADE_FTX_FTXG_29G.BGL by changing to ADE_FTX_FTXG_29G.BGL.OFF, the taxiway appears. However, they are not positioned quite right...there appear to be two different centerlines, one for ADE_FTX_FTXG_KPOV.BGL (I'm guessing) and the other for the original taxi way (P3D-again, I'm guessing here).
Also, with ADE_FTX_FTXG_29G.BGL.OFF, the orbx grass grows on the taxiway.
It would be great if this could be 'fixed' for P3D V3.3.
Anyway, I think the free airports, including this one 29G (KPOV) are great! You guys really do a nice job of populating with much better airports. This one (29G) looks very close to the real thing.
