Great observation and I totally support separating those two. However, I'd likely go with different naming. "Hunting Tasks" are official name for the Prey Hunting Tasks. The so-called "hunting tasks" from Grizzly Adams are not called like this or referred to as hunting tasks anywhere in Tibia (I think...)
Perhaps we could reserve hunting-tasks for the prey hunting tasks and use existing killing-in-the-name-of for anything related to Grizzly Adams tasks? Alternatively, we can also create a new tag paw-and-fur-tasks.
There aren't a lot of questions with the hunting-tasks tag that need to be changed, so I think a manual edit is OK here.
Thoughts?
