Hi, the classic ERA or vanilla version must be updated with BC / SL new backdrop mechanics.
The talent frame doesn't show up at all at the moment

Lua error bellow

Thanks !

You however didn't release the fix for 1.14.1 on curse

Yeah the update didn't show up

I run a modified version to fix backdrop on my own and I missed the previous release it seems.
Apologies we good then !

Thanks for your work :)
