Miscellaneous: Tinkering Clockwork Watchman Arms combine bug

[Bala]

Has anyone successfully done this combine recently?

I’ve made Clockwork Watchman Vambracers many times before, but when I tried today I consistently get the message: “You cannot combine these items in the container type!”
I’m confident I’m using the correct ingredients, and I’ve tested the combine in multiple Deluxe Toolboxes with the same result each time.
I didn’t have the droppable piece on hand to test the other Clockwork Watchman armor pieces, but I did successfully make Footwarming Boots, which worked as expected.

This makes me suspect an issue specific to the Vambracers or the Clockwork armor rather than Tinkering or the container itself. Or its just me missing something
