The Dev patches the game nearly every 7 days or so.
Please imagine that for every patch there would be around 2 or 3 hours coding and testing the trainer.
Also every Update would have it's own trainer, the site would be exploding. 😀
I think when the dev has the game in a state where he has to patch it one time per month it would be active.
The last POSTED update was April 6, then the one POSTED before that was March 16, but there's always a ton of postings that never get posted on the steam site.
The game is still in early access..
Apparently the version after 2 years (2 years of early access!) is like 0.129, WELL away from version 1.0 which is usually the release version.
Likely anything we posted would be broken in 1 week and we start all over again. Face it, you guys paid to be play testers and bug fixers for people making a game that was not even close to being done when you bought it..
