Mac I cannot be 'protector of the valley'

[Hwanhee]

[Mac OS, Single play]
I had done all the task in Adventure Guild, but I couldn't get the achievement 'protector of the valley'
Gil doesn't respond.
I think maybe it's because I've been playing this map for so long time.
I wanna get achievement legitimately.

Hi! Can you create a zip of your save folder and post it here, if it's still an issue?
