Seems some baseball cards in non MLB leagues (only tested Korean/Japanese leagues so far) aren't generating properly, and are not generating stats, or skipping a bunch of years.

All Star game cards are somewhat working (but seem to miss quite a few years from before 2014).
Not a huge deal by any means, but just thought I'd post it anyway.
EDIT: Australia is working fine, though some 2nd year players were winning rookie of the year (but that might be intended)
EDIT2: Taiwan is working for the most part, but still a couple of times the same issues above are popping up:
