This is true because they use some code of the ingame developer functions like all 'fast' cheats and invisible.
Could you please tell me what options use code from the dev functions? I want to avoid them whilst going for the achievements - thanks.
NumPad5: Easy Crafting
NumPad8: Fast Build
NumPad9: Fast Scan
NumPad0: Fast Hatch
NumPad/: Fast Grow
NumPad*: Unlock Doors
NumPad-: Unlock Developer Menu
I think developer menu only if you use certain features of it but I'm not fully sure. If achievements really matter for you then better dont use it as well.
Many thanks
Downloaded latest trainer and I got the same than you, weird. I will send a fixed trainer soon.
Thank you! It is much appreciated.
