Nice job! Keep up the great work. Looking forward to ur updates.
The trouble ur having with the AI lines U made not loading unless U hold the shift key down can be remedied by deleting the .BIN files and other . AI in the AI folder. They have old versions of the AI line and limits cached and CM uses them to load the AI data. If U delete the BIN files and the other .AI file LEAVING ONLY the fast_lane.ai and pit_lane.ai, the .BIN and other .AI file will be re-created by CM with ur new AI lines and track limits next time U load the circuit. AND no more holding down the shift key all the time :-)
