A serious issue I have now encountered with two leagues I've converted from 17 to 18 - no injuries to any major, minor or feeder league player in about a season of simming.
Both leagues are online leagues, and I've test simmed a whole season with injuries set to high, but still no changes. I've also double checked the injury check box is enabled - it is. Other online leagues that I'm a GM in have converted from 17 to 18 fine and injuries have been occurring as expected.
I've uploaded league files for both leagues to
ftp://ootpsupport.com/incoming/ootp/saved_games/
Called PBF.lg.zip and SBC.lg.zip
I've submitted a ticket for this.
