Getting master hunter as a build option deletes hunting grounds

[tabone]

As the subject states, every time master hunter shows up in my build options if the region has a hunting grounds already built the hunting grounds will disappear. Hunting lodge seems to be unaffected if both are present, and I'm uncertain if the same behaviour happens if only a hunting lodge is present because hunting grounds are in all my forest regions.

I think I understand what's going on. I'll note that as a fix to do, thanks.
