By either using the Slash commands /mdt or /manbabydungeontools or going into the options to hide the minimap button leads to following error:

Edit: Clicking on the minimap button leads to same error (opens the window though)

The same error is also thrown when using the minimap button.

this should fix the issue.

It didn't fix it for me.

@T3ll1nG Can you provide the error you get please? This fix did work for me on testing.

@Pashbee
You suggested changing line 570 in MDT/Locales/enUS

I run Win10 en-US and the gameclient is en-US too.

I get the same error message as before.

If you click the minimap button:
2x ...eManbabyDungeonTools\ManbabyDungeonTools-3.3.4.lua:1042: bad argument #1 to 'random' (interval is empty)
[string "=[C]"]: in function random' [string "@ManbabyDungeonTools\ManbabyDungeonTools-3.3.4.lua"]:1042: in function UpdateBottomText'

If you use /mdt or /manbabydungeontools after wiping saved bugs
1x ...eManbabyDungeonTools\ManbabyDungeonTools-3.3.4.lua:1042: bad argument #1 to 'random' (interval is empty)

the PR got merged but you're right it does not work because of case sensitivity on the lookup. I am sorry. I will fix and put a PR in again.

@T3ll1nG fix here - I could re-produce the error you were seeing. Please let me know if that works.

@Pashbee that fix works just fine.
Nice 👍

@Pashbee i had the same issue but your fix + changing the casing worked for me as well
