0.96.22 long "loadings" in the swamp

[Misterpiece]

After installing the experimental 96.22 and importing a relatively new save (one character only from Rock Bottom start, with less than 10 combat skills) I tried 3 times to go from Waystation (Admag) to Shark, passing through the Swamp village on the way. As soon as I approach the swamp (I noticed several new swamp trees have been placed in the area) the game pauses and it loads. Compared to before the update, it takes at least 5 times as long as a regular "loading" while moving around.
