yeah when draco spped = 7 and mob speed = 14 you run the risk of losing your entire train when crossing over walls, buildings and other things that normally cannot be crossed. I used to be able to vac with draco spped 11 and seting the naggro speed at 41c000000, but as I have only recently resumed hacking, that particular naggro script is no longer working for me. So now I am using the vac and naggro script all in one combo, which is not as flexible as having differnt ones for each action. (sometimes it was desireable to have a naggro without a vac and speed at zero, dun's)
In summary, slow down.
If someone would care to post how they can reliably vac, and maintain thier train at a speed higher than 7 ( ie ten or 11.5 liek i used to be able to do), with a mob speed around 419000000 + that would be refreshing.
Thanks
