Used most recent build (shows 25.10 Build 95). My pitcher had carried over a scoreless inning streak from the previous season. In his first game of the season he pitched 7.2 scoreless innings and left with 2 runners on base, which the reliever who came in immediately allowed to score, meaning his scoreless streak should have ended right there. Here's his game log with first game of the season at bottom where he was charged with 2 runs.
He pitched a shutout in game #2 and then in game 3 allowed 3 earned runs. After that game, it published an achievement on screen that he had pitched 31 scoreless innings and updated his historical streak record to show that too, as you can see spanning the games that included that first game where had allowed 2 earned runs.
I've FTP'ed the league DAT files to OOTP site as CBLBug_leaguedatfiles.zip (pitcher's name in question is Corey Meloni). Have manually played out almost 30 full 54-game seasons over many years so also wondering if there's any possible way for me to manually edit that ended streak history to fix it back to his previous scoreless streak record of about 21? The pitcher in question is one of my best pitchers so don't want his historical record to be buggy if at all possible.
Thanks for reviewing this bug in any case. I think I'm right that he shouldn't be credited with a scoreless streak that included some ER charged to him, even if it was the reliever who allowed the inherited runners to score.
