I am using junction25 and have the required 1 police and hospital set up. But no specific AI paths or traffic lights, i can edit a map, but it always gives me that message when i try to run a map i created from scratch
i think that is either compression bug or scripting block changing bug, try recompressing the map in j25 by selecting, copyng and pasting onto same place and saving. if that doesnt work, are you using existing game script or empty script? try empty script.
