A couple glitches in Quest for Glory II: Trial by Fire

Dumb video but I was bored. I was playing this game recently and wondered what would happen if you go back to Shapeir after you take the caravan to Raseir, so I tried it. (Keep in mind that the perspective is flipped when you are in the southern half of the desert, so north is down, etc.) Most of this video is just me running across the desert, so skip to 4:17 if you don't want to watch that. Shapeir is on the north side of the desert and Raseir is on the south, so after going to the northern border of the desert, go west 400 screens from Raseir to reach Shapeir. When you enter, the caravan scene plays again but Khaveen's scene doesn't, so you're stuck there. I also tried this in the remake but it doesn't work. In the remake you automatically end up in Raseir's inn sometime after night falls (I think midnight) and you don't have enough time to reach Shapeir before that. The second glitch begins at 5:45. The desert is 1,000 screens long, and loops. The looping point is 300 screens west of Shapeir (or 300 screens east of Raseir). However, the looping doesn't work properly. If you move east past the point where the desert loops, you'll also end up one screen south (and crossing it west will put you one screen north). So if you are on the southeast corner, then go east, you'll be pushed past the southern border of the desert. Going north from here leaves you standing inside the mountain. Then I decided to see what happens if an enemy appears while you're standing up there.
