Message:	[quote=Darwin] The error message, I think, was something generic about a script error and the premature exiting of the function was due to where I had placed that line. In either case, your suggestion worked and I moved the line to below setting the task complete so even if it did error again, the task would still be marked as completed. The players are loving these things and wanting more. Great job on such a simple and flexible questing system. :) [/quote] Message to be posted (in English, please).
