Hi there,
Thanks for the detailed information, I've managed to find the issue and you were right: it was at our end
It looks like changes from our Development repo were erroneously pushed to the Release repo, which explains why I wasn't able to replicate it at my end. Simply uncommenting the Resources.Load line and removing the line below it will fix the issue, but I'll PM you an update and push this to the Asset Store.
All the best,
Joel
