single player mode. originally i tried towing a boat that was a boat on fire mission to test how well my ship would tow. it glitched out and put me on a map with no islands, only water and other weird problems. today i tried a towing mission, and the same thing happened weird issues then not responding game, had to use windows task manager to kill it. i briefly tested out the idea of speed. i noticed under 30 MPH it seemed fine, the second i went over that, the game freaked out. i used the proper conversion for speed in MPH. over 30 it cant handle it it seems.
