I'm playing DaBigBabes 29B scenario (with some minor edits) on the extended map, and I'm having problems with ships disobeying orders and going to Aden and Mombasa instead of where they belong.
First, I noticed that any ships disbanded in Abadan teleported to Aden. This was a problem because all my tankers that were needed to carry fuel from Abadan ended up in Aden, where there was nothing for them to carry. I found a work-around for this by not disbanding any ships in Abadan, and just leaving all ships in an undocked TF. That solved the teleporting problem.
However, I've found that TFs that load at Abadan will change their homeport to Aden after delivering their cargo. If I set the destination and homeport to Abadan, the TF will go there, but I have to keep a careful watch on my supply TFs to catch them before they get back to Aden.
I also find TFs on their way to Mombasa, after I have sent them to other destinations. I haven't figured out what's up with these TFs.
I suspect a problem with the pwhex file, but before I try to edit that I was wondering if anyone had seen similar issues and had already come up with a solution.
