I never had a issue before with a trainer so I never had to use it. Thank you for your info.
Which faction & time period did you play as?
I tried Liu Bei at 200 and 194(?). The result did not give me a one turn reform. I was also unable to pick a reform after the normal amount of turns. Additionally, the 5 turns to go UI notification was absent after using the trainer option.
Just wanted to let you know that someone else experienced the issue 🙂
