Quoted from markmon:1.22 was not released. 1.2 was the last release. Someone ripping it off a machine shouldn't count. So in that sense the little things do count like the magneto lock improvement. But I agree with you on the rest of the bugs though. Valid points indeed.
If you want to nit-pick, 1.21 was the last official release posted on Stern's site before the Power Pack...and it didn't fix the Magneto lock. If you want to give 1.23 credit for fixing the lock timing...1.23 still creates more bugs than it fixes and adds very little except jumbled up rules that need to be tinkered with by the user to play well.
1.0 & 1.1 shipped with first run LE's
1.2 released by Stern and broke the lock timing
1.21 released by Stern but still didn't fix the lock timing (+ cool Xavier mode and Sentinel intro)
1.22 shipped on later run LE's and posted to the internet. This fixed the lock timing.
1.23 POWER PACK!
It seems with 1.2, 1.21 and 1.22 things were looking up and heading in the right direction. 1.23 seem like someone went in to work and just started moving lines of rule code around to make it easier.
