Our 60's league has a reported (4) starters making consecutive starts.
Jim Bunning started game 54 and 55 Gary Peters started game 54 and 55 Larry Jackson started games 54 and 55 Sonny Siebert was the odd-ball starting games 53 and 55
Our 90s league had the same problem. One manager said his SP's were all out of order. For my team, it was the last night of the season, I planned to rest Roger Clemens, but he ended up pitching on 1 day of rest. The other manager said it happened in his other leagues as well.
Same issue took place in the 70s leagues too----pitchers went on short rest----pitchers who were scheduled to go were skipped for guys with one day rest. No word from SOM on this.....
