Trying to re-do pet treasure chest that's massive and am working on manually moving it out and starting small instead. Wondering when it shifts over so I don't have to guess?

a tc needs to have at least 300 items in it to switch from drag and drop.

you can pick which method you use with the option beneath the "order treasure chest" button that says "You're using Drag-and-Drop. To switch to using Click-to-Move, click here."
