Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes
Provide extra information to complete the original description of the issue:
The whole airport is duplicated, vehicles buildings etc. Even worse, with SU12 I’m getting reproducible CTD at TNCM in various aircraft. Uninstalling TNCM is not a solution because it’s packaged with TFFG which I don’t want to lose.
