It's me again (maybe I should consider registering
)
Ok, I just found out how to get my HQ back. I discovered that \DATA\MISSIONS\MIS_1004.RTX is the file for 'Four Islands', so I copy/pasted [GLOBAL_MAP_SETTINGS] from that .RTX to MIS_0000.RTX. Maybe now there are other players too (don't know if that wasn't the case earlier, I hadn't explored it then).
Ok, now I am really ready to play
I'll let you guys know if it works. If you want the files, just let it know!
