Minor bug i guess,..
Tried updating the profile (all of it) and got the insufficient funds error message for the avatar.... The main page will still list the "profile change" though, neverminding the fact that 0 change took place :))
I guess the solution would be to either change it so that - when trying to update all at once - text and link get updated first, and then it will check for teh avatar funds; eventually giving out the error message, but definitely saving the other stuff. OR check boons for avatar first and halt the whole "subroutine" (so the update message won't appear on the main page) if they're insufficient..
