/finditem has a bug (that only started recently) that it will not "find" items in bags that are on the right side of my inventory (I know..strange).
For example, I have a macro that makes blessed dust of tunare in a kiln that has been working GREAT. Now, the macro will stop half way through and I have to move the remainder of the supplies over the the left side inventory bags.
I've noticed this with all my macros that involves combining things in a container that is stationary (ie: kiln, brew barrel, forge)
