> #18453 introduced a bug in computing the weight for elements in the
highest weight Nakajima monomial model (mainly, the weight of any highest
weight element is 0). I have fixed it on this branch, but if this will not
be getting in soon, we should split that fix off into a separate branch.
If there is a bug in Nakajima monomials, I suggest that you split that off
(since I will have quite a few changes to this patch) and discuss it with
Ben (as he did most of the changes in #18453 to Nakajima monomials).
Best,
Anne
