Once this initial call has failed, all other Knapsacks calls fail with "Couldn't get UUID for player".

I also would love for this to function on 1.9+ because of that failure it also cannot be used on anything newer than 1.8 :( This is the best backpack like plugin out there, all of the others require you wear the backpack and use a "key" which is absolutely dumb and annoying to do taking up one of your slots on you bar to use it. Yours permitting a simple right clicking on the pack anywhere in the inventory to open it is the best thing I've found. Looks like I won't be upgrading to 1.1 (dumb roll over of numbering) nor 1.9, because of this plugin not functioning on either. This is a vital necessity for MC to be enjoyable, without having to make runs to town constantly to dump goods off.
