Hello, Isiah here.
So I believe I know what the issue is and I can probably prepare a hotfix by the end of the day today, but first I want to get a bit more information. I think the issue is purely with the \I text code, but if you can, can you verify that other text codes are working? I believe they should be. I can test them myself when I've got the time tomorrow if you can't look at them tonight.
Thanks
