Ok, I guess I'll stop trying to get support on this.
How do I even start to support you on something I cannot reproduce ?
I'll jump in here and report the same issue. p3d v5.4. aircraft type doesn't matter.
KORD will reset after 30 seconds (and repeat). SODE reports disconnecting from jetways.
There are also gate objects floating in the air. I've tried restart couatl and rebuild cache. Doesn't help.
Finally after several repeated restarts of KORD, the scenery stops loading. Addon manager will not load, couatl does not appear in the add-on menu, but appears to be still running
