Civilization 5: Gods and Kings Cheats
I can't really help, but have to say this happened to me also when I used it, it also got attached to the actual SAVE FILE and not the "game session" as that save got 1-Turn Research even if I rebooted my PC.
Anyway, hopefully now the developer of this "God-like" trainer is aware of this little thing, and if a new trainer ever sees the light of day, it will hopefully be sorted.
i just wantet to thank you for releasing this new Trainer and be sure that at least some member appreciate you're work.
Thats why i bought Lifetime cause you're doin an amazing job.
