I hope I'm not wasting your time and I hesitate to even post this because I know so little about zquest.
But here I go.
I have been building an overworld and a dungeon in earlier builds, and moving it to the latest build when they come out. In my dungeon I have a insta-warp to a screen on the same dmap and every time I try to use that warp in the player it crashes, and I get the usual windows message
It's has worked fine until I put it in the 718.
And there is a twist the plot, I have been putting my save file from the other versions in the latest build too.
If I use the saved file it works, no problem. It only happens if I register my name and start a new game.
I even downloaded the build again and tried it. Same thing.
PM me, and I'll send whoever wants to fix this a link, and how to get to it.
