WowAce

AceDB has been updated to fix the "regionKey is nil" Lua error:

Ace3/AceDB-3.0/AceDB-3.0.lua at master · WoWUIDev/Ace3 · GitHub

but Shadowed Unit Frames and the other addon authors (including Bartender4) that embed AceDB need to update it to the latest version (minor version 28).

Currently, on the classic PTR, `GetCurrentRegion()` returns 72 (at least for me) and it can be random I've heard so you can't trust it. As shown on the link above, the updated AceDB version has a fallback. This version fixes the problem.

This is the full error:
