Not sure if this is being worked on but there seems to be an issue in regards to service time with many players that has carried over from last year's set. The thing they have in common? It seems that most players who missed some time in the 2014 season due to injury have issues - I am not sure if 2015 is an issue or not. I made a few posts about it last year in the roster thread in regards to specifics then I noticed the trend. I am not too worried for guys who have reached at least 10 years in service time but for anybody less than that it may be quite a big issue.
Some examples:
Jurickson Profar, Matt Harvey, Jose Fernandez, Adeiny Hechavarria, Troy Tulowitzki, Clayton Kershaw, Aroldis Chapman, Masahiro Tanaka, Henderson Alvarez, Jarrod Parker
Profar, for example, is at 67 days in the roster set but has missed two full seasons in which he did accumulate service time. It should be 2 years and 67 days for him. Others, like Chapman, are off by only 10 days.
From last year -
