Thanks, I know this kind of thing can boomerang into other problems, as evidenced by the fact that these 3 examples seem to have been triggered by 2 different parser fixes listed in
versions.txt, and the final examples didn't involve a while() loop yet the description of the fix showed the change was because of while() loops.
Hopefully there will be more people willing to test the beta so anything that might be caused by this would be noticed before any official release.
