I'm not quite sure where this problem emerge, but I just got the following strange result
Given you have opened VisualEditor for editing
When you open citoid for automatic cite harvesting
And fill in https://arxiv.org/abs/1905.04206
Then the result should have K. Darshana Abeyrathna as first entry and Morten Goodwin as last entry
Now it has Morten Goodwin as first entry and K. Darshana Abeyrathna as last entry.
It is customary that those that do the actual work is written first and honorary entries are placed last. It is thus quite important that this is right.
