A couple of customers have reported issues with autogen colliding with some default airports.
I've updated the airports here to include the correct exclusions and attached here. Please download, extract the folder and drop this in to you Custom Scenery folder, overwriting the folder already there.
This fixes these airports:
LEAL
LEBA
LEMO
LEOC
LEMX
LEMG
Please report any others you find here, and we'll get these patched to Orbx Cen
