I have tried this on two different pc's (windows 7 prof. and windows 7 enterprise). Adrift crashes when modifying a specific direction connection. Thus I cannot modify my map. I can provide the .taf-file and instructions where the program crashes if needed.
This was caused by an infinite loop on the map (Room 1 down to Room 2 which goes down to Room 1) and each room was on a different page on the map. Fixed.
