Expected behavior

Fletcher requests wool when wool is insufficient. They should request the player to fulfill the request.

Actual behavior

But instead of request player to give white wool. they look at the recipe list, first, the cycle is wool -> string -> wool -> string -> wool ....
after remove the string -> wool recipe, they instead request wool -> gray wool -> wool -> gray wool -> wool ->gray wool -> wool ....

Just confirm with my friend,he has 1 fletcher (but 3 fletcher's hut)

We do have cycle detection, that's the weird thing.

Latest update:
1 fletcher's hut and 1 fletcher now. still have the issue.
the farmer also have a cyclic recipe requests. This is because he added two recipes that convert things forth and back. like hay -> wheat and wheat -> hay. I have already ask him to remove one of the recipe to avoid the issue.

But I would suggest the code should able to detect an circle within a graph. there are some algorithm that can detect that in directed graph.
