Crashless bois. Run begins at 23:00
Update 12/30/18: My first video! According to Youtube's stats, people are still watching this vid. But, this was my slowest run! The title of the category was changed from Glitchless to No Major Glitches for clarity's sake; the rules are the same. I improved this category by over 20+ minutes since this was uploaded. You can see that run, a 31:52 (loads removed time) here:

The route I use introduces the use of a specific item (Scroll of Windform) that certain merchants could possibly have, which can be repeatedly attempted by quicksaving outside of where the merchant is, and quickloading if they do not have it. The rate of them having the item is very low so this is a very RNG dependent route, but technically speaking it is the fastest way to do the run. You lose about 5-6 seconds in game (maybe 10 seconds real time) each attempt.
Alternatively, you can choose not to go for the Scroll of Windform, which is essentially a more refined version of this route including other tricks like selling scrolls back to buy at a larger increment, better menu setups, better use of teleportation spells (mark/recall/intervention spells) and much better execution. Link to my most recent best run, a 36:23 (roughly 40 mins in real time):
