Ok, I've done some post regardin Madeira troubleshooting for many products. Some of them are similar to those experienced in the previous product, common thing is that they're mostly caused by 3-rd party addons.   If having mesh/coastline issues please check:   1) If the default files were excluded correctly   In FSX/P3D main/scenery/0502/scenery check if you have those files disabled/removed APX43200.bgl CVX4320.bgl   If not move them or change
