Oh look, questions I can answer!
So, we're not entirely sure when we're taking the Halloween items out of the shops~ BUT, we are going to leave them up for a decent amount of time, only because there are quite a lot. And Diana and I (if we have time) plan to release a second batch of items. It may not be as much, or it might be. It all depends on what we can get done for you guys.
But the primary bunch of items (the ones you all have, and in the shops, etc.) are going to be around to hopefully give you guys time to buy them. <3
I'm also planning on releasing a free small set of Halloween-specific items that everybody can get, but only release them for a short amount of times, much like the Commemorative Wings~
Also trading isn't implemented yet, but you
can donate to other people.
And yes! Stacking items is wonderful! I hate when on a site I have multiples and they just clutter by all going individually in a row.
Such a waste of space!
