i know the problem, i guess these nodes are not part of the difff.xml as they are part of the addonpack. so not programmed by devs but contributors and contributors don’t edit the difff.xml.
Yeah thought we added it in diff (which also works for plugins), but seems this one escaped somehow :)
Easy to add again indeed, pin naming is the same tho so if you have a red Interleave node you should be able to type Vector (Spread Join) and it should relink (bit painful if you have 20 of them i admit).
