I am attempting to perform task 5/15 which states "Time to show who's the best captain of the sea! Engage in a ship battle and achive victory!" but when I win it comes back to the same task. After winning in a ship battle it gives me the congratulations message, but immediately goes back to task 5/15...Any suggestions?

NOTE: I have attempted to alread quite the quest and restart which did not resolve the problem, and I have also already logged off vmk and logged back in to see if this would resolve the problem.

Same thing occurred during the "Adventure Through Inner-Space Quest" task 7/20 when getting 30,000 credits on jungle cruise, once completed it says congratulations you click on next task and poof....Your back at task 7/20 to get 30,000 credits on jungle cruise...

CONGRATULATIONS MESSAGE AFTER WIN
31086
LOOPS BACK TO TASK 5/15
31087

That happened to me, but quitting the quest and restarting fixed it for me. I'd try the "contact us".

Happened to me, I had to find the skulls all over again when I did the pink car quest O_o

This happened to me on a friends account i was helping them out and it kept doing it and doing it. It took me a few days to get past it.
