Hey @Fabby 
I’m currently maintaining the plugin for James.
I’ve added Retort to the plugins you can submit a bug report for here: Bug Report. If you submit one there I’ll automatically get assigned to it and resolve it relatively quickly (within a week most likely).
I’ve made a bug report for this one, and after a bit of work (this one was actually a little tricky!), I think I’ve resolved it. If you could update and let me know how you go in the bug topic.
