Hello, do you plan to update this addon for classic Era as well?

Since it seems to work I've tagged the classic version as compatible with classic_era on CurseForge etc.

I don't know anything about the Masque support sorry. I think it would be best to try to contact the author of that addon and see if they can help.

I think the classic client will also work on classic era, but I don't play either so I don't have any way to test it.

I tested it today and it seems to be working fine, no errors.

Sadly the Masque plugin doesnt work as it should but i guess thats because its for retail only.
