Can't customize Fox base wolf??

Hey, I got a fox base wolf recently, and I've been saving up to fully customize him. Now that I can, I went in to go do it but.... it seems the  customizer, as it wipes out all preexisting markings when you go to it, won't let me pick the fox base again! It just shows all the bases that would be available to any other wolf. Are fox wolves just not customizable in the customizer, or am I missing something??

You can only use custom bases and markings in the customiser, anything that is only available from applicators or breeding will be wiped when you customise them, such as the fox base. 

You can still customise them with Marking Applicators but this is a more expensive option and a little more tedious too lol. 

Dang, that sucks!! Explains a lot though, guess I'll have to do it the hard way. Thanks for replying!
