Crashes the game when right clicking in an empty cell on the favorites bar. Error is:

Thanks for the heads up - fixed now

Unfortunately I am getting an error as well when trying to make new way points:

I thought I had posted a response last night, but I guess I was sleep-walking.
Anywho, this should be fixed.
Please let me know if otherwise. Very sorry for the incovenience.

Just updated and works like a charm. Thank you for the quick update!
