Fishing Bug... maybe... at least it doesn't make sense.
I was fishing in Dravanian Highlands and there's one particular fish that doesn't really make a whole lot of sense... the sweetfish.
On several occasions I would catch a HQ sweetfish, mooch it, only to get a normal quality sweetfish back. The whole point of mooching is to get a bigger fish right? So why am I mooching smaller fish? (the screen shot shows that these fish are like half the size too.. well the second one is I guess =p)
