There can be plenty of reasons for the perpetual loading, one of that is missing assets which is entirely my fault. I have a planned fix, just haven't had a time yet. Will try to do it this weekend if i can!
As for YEP dynamic title screen, I did not make a compatibility for it. So can be a reason too, will keep this in mind when updating the plugin.
Edit: Updated! Haven't take a look at YEP Dynamic Title Screen yet though. Next time!
