Thanks, i'll remove the airgroup and see if it was the cause of the CTD
Are those GWX classification types you listed?
GlobalExplorers list of types differs, ie: theres no replenishment Type=100, or minesweeper Type=5. Unless those groups exist in SH3 but are unused.
I did a "find" on Type=100 in Campaign.RND and nothing came up.
Same with Type=5
If i'm right in assuming GWX is a modpack done by a group of players and not the Devs, it means they're unused in stock or there IS a way of adding groups.
I just gotta find it lol.
Or do a lot of Campaign.RND editing

But i'm basically a lazy so and so, so i'll have a look for the classification file b4 i start editing

I don't have the editor for MIS files though, tried downloading S3D but the download failed and i got the message " a cabinet file necessary for installation cannot be trusted. Please check synchronisation is enabled and the cabinet file has an authentication certificate". Double Dutch to me lol.
Failing that i'll do as you suggest for the liner entries and wipe out the PPL line, but i'll have to add the medium troop transport and hospital ship manually convoy by convoy.
