Describe the bug

The WoW Classic Era client got updated today and now when you load into the game (or do a /reload while in-game) the following error shows up:

You can get the addon to work by opening the options via command /TMW which then launches this LUA error:

Closing this error then allows the addon to work properly, from what I can tell.

Looks like Blizzard merged in the 10.2.5 API changes without bringing over the deprecations...
