If your Midway files from RSRDC are not "spawning" almost exactly on-time, then you'll need to look in the original files with a text editor, and copy the lines exactly as lurker had them over into your edited files. If you used the Mission Editor at all on lurker's files, the ME will add lines back into them, and change some of the settings for the DelayTime and a few other oddities that I don't understand why Ubi did that... It can be very frustrating to have to use the ME for your graphical view of the world, and then come back in with a text editor to "fix" what the ME did to your files...
