Description
Upgrading from Autorank v3.3 to Autorank Beta Build #305 messed up play times.
Players's local and global play times got reset and/or decreased in value.

Error log
Does the following error log have anything to do with it? Console posted it last time I restarted my server:

My workaround
Recreating Autorank database.
Because of how I use Autorank only for ranking Guests up to Friendlies, the playerbase generally seemed okay with their play times being reset. It is not the optimal solution, though.

Versions
Autorank: Build 305
Spigot: 1.7.10-R0.1-SNAPSHOT build 1649 (20141001a.bps)
Bungeecord: Build 1015
PermissionsEx: 1.22.5

Kind regards,
Sinuce

EDIT:
I see a new build 306 is out.
Nevertheless, with this thread I wanted to share the issue I experienced.
