I haven't been on for over a year & I have almost 300 items in my inventory. What happened to the quick stock option?

I used to just go into my shop & move everything to where I want them to go ._.

Welcome back! You can still use quick stock, but recently the shop system was changed and you need to create a new shop to be able to move stuff around. More info here.

Your old shops still exist and people can buy items from them, but you can't add items there or change prices. Basically this means you'll need to create a new shop to use quick stock ^^

Oh! Thank you very much for your help :D
