I'm getting this error in 12.0.0 with the latest RangeDisplay.

UPDATE:

Addon updated - v6.3.0 - contains this fix

Just download or update it via your addon manager of choice :)

Thanks to the author for the quick reaction.

FAN FIX (unofficial, use at your own risk):

- Just resolved it. So far no further errors on prepatch for me. Tested in dungeons too.

- Additionally, I've submitted a pull request on github for the author to review, test and if he's confident in the fix to push it officially. Here's a link to it:  https://github.com/mitchnull/RangeDisplay/pull/9

If you wanna try my custom fix, follow these steps:

1. Find and open the file `RangeDisplay.lua` inside the RangeDisplay addon folder. (You can use any text editor, I use vscode or notepad++ for these things)

2. On line 231 - Find the function `local function = checkTarget(ud)`

3. Replace the whole function with this code: https://pastebin.com/3nKf7FJt#3Df72Zqx

4. Lastly, open the `RangeDisplay.toc` file and make sure 120000,120001 versions are listed on the #Interface line

That's it. This is an UNOFFICIAL fix that I made, because I wanted to stop getting errors and still have the addon work for me. 

You are using this at your own risk if you choose to give it a try, like with all fan fixes. :)

Hope the Author confirms everything's good and publishes an official update, either with mine or any other fix that prevents errors and restores functionality to the addon. 

Have a good one! o/
