Set Taxonomy Parent

After playing with it a lot more, it turns out that it is accomplished with set field value.

1. Create the term with Entity: Create New setting the type to Taxonomy term: MyVocabulary and the Entity label: what I want the term to be. Create a token, ie. new-child
2. Entity: Set Field Value: Field name: parent. Just the word 'parent'. No brackets or new-child:parent:tid or anything. Literally just the word 'parent'. Field Value: the TID of the parent. I used a token by loading the parent term first, then grabbing the TID that way.
4. Eventually save the new term, using Set Field Value or Save entity

Actually, parent is a field of type entity reference to the term entity. And yes, setting that with the set field value action is exactly what's needed.

Not sure about the status of this issue, though. As you assigned it to yourself, it looks like you're dealing with it on your own, not expecting input from other, right? That field "Assigned" in issue metadata is meant to show, that someone is dealing with it. If that's filled, everyone else assumes, there is nothing to do for them.

I didn't mean to assign it to myself, nor do I know how I ended up doing that. I was mostly answering my own question for future reference, in case someone else was struggling with the same issue. I indeed have solved my own problem and no longer need any help.
