Mixed-up zone points with 0.5.2 db.sql

[Drawde]

I'm encountering a strange problem with the zone points in the 0.5.2 db.sql.
They all work, and are in the right place, but their destination zones and/or locations are mixed up.
For example:

Butcherblock-G.Faydark goes to Dagnor's Cauldron
Dagnors-Butcherblock goes to Kedge Keep
N Qeynos temple teleporter (this is a zone point, just one that goes to the same zone) goes to Qeynos Aqueducts
N Qeynos-Qeynos Hills goes to Qeynos Hills, but to the W Karana zone point, not the N Qeynos one

This is using the 0.5.3DR3 binaries. The zone point and zonepoint_raw data in the DB is from the 0.5.2 db.sql, not
from my DB or anyone else's.
However, I also encountered this problem with the latest MyWorld DB.

Anyone else experiencing this problem? Is it a DB problem, or a code one?
