Yeah she said this again in the drawing stream and I actually heard it this time. But this time she also said that she's going to get another merch run 'later in the year' when things are less busy (3:55:22):No she specifically didn't do any because it was so close to her birthday.
I get it, especially for Mumei having birthday and anniversary just a couple weeks apart, but ironically I think that makes it harder to plan for unless it's telegraphed by an announcement or new outfit or something. But when merch just drops out of the blue...I've had it happen before where I was thinking, "Ok, nothing else is coming up soon." so I ordered my merch, and then some surprise merch dropped like 2 days later.
