A Land Fit for Heroes
Playing as any of the Welsh kingdoms, complete the main campaign while keeping heroism over 20 and never falling beneath 20.

Earlier, this achievement needed to be returned to the game version to be unlocked, but last year the return version feature was removed, so this achievement cannot be obtained now.

I have maintained over 20 points of courage throughout the entire process using two countries from the Welsh camp, and I have tried many times but cannot unlock it.

Is there a way to obtain this achievement or fix this bug.
