I dropped mine in and all seem to working. I'm just starting off season so a long way from playing games in them, so can't say I won't find an issue. What I did was my Wrigley Field first, confirmed all was well. Copied in files into three or four more parks, confirmed all worked. Then copied to all parks but did not check them, assuming (I know, ASSUME

) they worked too. So approx. 5 confirmed and the rest assumed to be working.
Of course backup the ballpark file before making changes.
