While donating pumpkins to Fantine I got this error message:

SQL Error! Oh no, our database is acting up. Please take this error and post it on the appropriate thread in the forums:

DELETE FROM user_items WHERE userid='241941' AND itemid='156659' LIMIT 1

This has happened a couple of times. If I go back and click the same pumpkin it will donate successfully.

I also got this error.

DELETE FROM user_items WHERE userid='103228' AND itemid='184573' LIMIT 1
