I was trying to hold off discussion until tomorrow, but I will clear up a few things.
- Since the engine was re-written in a new technology last year, there is currently no way to apply a new engine version on a world-by-world basis. I plan to work on that in the future though, because there are times when it's necessary. Suffice it to say, it's not an easy task. This update is mostly minor fixes and tweaks, and the more significant changes were basically "across the board" changes, so they should affect all teams pretty much evenly.
- With regard to the change to low start ratings: I'm not changing the upper limits, just basically bumping up the start rating to the point where improvement will be more reasonable. So for example, instead of a guy with a 2 rating in Defense with a max of 58, now he would be maybe an 11 rating with a max of 58. This is temporary fix until there's time to redo the player improvement logic, which would be a major change.
