Miscellaneous: Tradeskill Error Message

[skottomania]

I'm not sure if this is technically a bug or not. I've noticed lately that when I combine something (most recently with Research and Brewing), I'll put all the components together in the Elemental Grimoire or the Brewing Barrel or whatever, hit "Combine" and then either succeed or fail. I'll still get the skill up, correct message of failure or success, and the item (if successful), but then I'll get the message:

"ERROR: String not found. (8053)"

Other than this error message, everything else SEEMS to be working correctly. What does this mean? And is it a bug or am I posting in the wrong forum? (If I am, I apologize)
