I dunno, we never designed this one for co-op so goodness knows what might be missing. I see you did copy the ai file from SP though, so its not that and I have checked the info file, that shows a co-op mode as well.

A long shot, but try renaming it from 48 to 16. Go to the maps info file and open the bandomeer_refinery_assault file with notepad. where it has an entry for co-op, change it from 48 to 16.

I'm saying to try this because dedicated server support tends to default to 16p map sizes for co-op, larger ones aren't recognised by the bf2142 gamecode, unless you know how to edit things server side.

PS< doing this will prevent you from playing in online servers for FirstStrike unless you back everything up and reload the default files.

Don't know about the debug file. As for the local server thing, just try what I suggested. Dedicated servers run off the same mod code as local. In fact if anything local servers tend to be more stable.

Unfortunately, there is no debugger for BF2142
