Its stable and has 1.1.0 Patch and only one older version...
Why has it been put on hold?
STATUS: ON HOLD - This game is currently patching very frequently and/or is early access with few downloads. It is counter-productive to continue updating the trainer under these circumstances. When the title becomes more stable and/or is out of early access, it will be re-evaluated for an updated trainer. Trainer updates for this game may still be released intermittently while in this status depending on our current workload. If you want we will gladly retire the game. Keep complaining and we can see what happens.
