Hey everyone. 
In the last two weeks this game seems to have received five (yes, five) patches. Aside from the fact that five patches to a game in two weeks is very excessive (not even a beta/early access game updates five times in two weeks), at least one of these patches probably made the trainer incompatible with the current game version.
The last update at the time of this post, on the 6th July, introduced a PvP feature, it seems.

I see that you do not have an option to vote for an update for this trainer in the WeMod desktop app. This link will explain why: Why can’t I request an update for a game? - WeMod Support.
Thank you for your patience.
