A few things as I'm back and on a new PC...

Heya! I wanted to get back to roleplaying...but I'm having trouble finding the Pawsome Items pack? Was it truly removed? Also...I have redownloaded Mass Markings twice....and when I pull up my characters I can't see any of the Markings, they worked fine on my other PC so I have no idea whats wrong. + Marshmellow tails, I know the Twin Tail marking isn't working well but there are others... I'm not sure what I'm doing wrong here so help is VERY appreciated~ XD Thanks in advance!

I haven't heard of the Pawsome Items pack still being around. The ones that are used right now are Legendary Markings and Legendary Items. You most likely are receiving the white marshmallows from using Mass Markings instead of Legendary Markings

So far, the Legendary Markings/Items are the only ones that I know of for the new update.
Those that MorgraWolf linked nicely there for you. 
Also, because you are seeing marshmallows is because the Legendary Markings have extra/more markings than the Mass Markings do.
