It’s an amazing trainer, thanks by developing it.
As far as I tested, only cheats 1, 8 and 9 doesn’t break the ‘runtime/statistics checkup’ and block achievements.
I also experienced the issue of auto-setting speed to 12m/s when loading the trainer and blocking achievements, but a workaround I found for this issue is to load the trainer only after researching the first upgrade tech that gives more movement speed, and then saving the game (may require restart, or not).
After this new game update (Version 0.9.24.11182), those cheats (1, 8 and 9) work partially… and just sometimes.
PS: not tested others since it will break up the game statistics and block achievements.
