Indeed MrAntifun, it would be great, if You update RimWorld trainer up to actual version - V0.12.914.
As my predecessors noted - trainer from version V0.12.911 is working on actual version (after file name changing), but it is pretty unstable (game freezing and many many lags).
I understand that You have much to do right now, and this site isn't the only thing that You are responsible for, but we hope MrAntifun, You will add updated version soon.
Thank You for Your time;
Sincerely,
Sh33p.
