untangle generates number of items to replace is not a multiple of replacement length warning for some methods

[djwalkr]

When untangling two large dendrograms I get "In weights_for_order[order_x[order]] <- weights the number of items to replace is not a multiple of replacement length". There are no NAs, the dendrograms plot normally individually and without untangling. Untangle methods "label", "ladderize", "random", and "DendSer" all work without generating an error for the same data. It is only when sides are permuted that the error appears. Presumably the weighting function is generating some kind of NA? These are only warnings and the dendrograms draw - with results comparable DendSer

Hey @djwalkr
Thanks for the report.
I'm not sure how to address it.
Any chance for a small reproducible example?

(otherwise, I propose to close the issue until such an example will be available to debug and fix)
