Duplicate Foruma Errors
I started getting duplicate formula erros about a week ago. Does this mean that the problem has to with a character called Mason? And is it a problem? The character I was working with "Nick" seemed to work OK.

Comments
It probably means there are two different characters called Mason on your system, though I see onyl one at Daz. Ideally oen or both of the creators will chnage the name (e.g. adding their initials in fron of Mason to distinguish them). It is probably worth opening a support ticket to report this, even though it is unlikely to be a fault with oen of the characters as such.
