[Bug]: Can't move Icons in DF Beta

[Ehland]

WoW Version

Retail

TellMeWhen Version

TellMeWhen-9.2.3-17-g6c4845f

Describe the bug

When moving an icon from one slot to another on DF beta a Lua error appears and prevents it, furthermore, there is an error under "Who to watch" section of buff/debuff icons. I have reinstalled TMW and tested on multiple chars and get the same issues

LUA error: TMW lua error.txt

Who to watch screenshot:

Export Strings

N/A

to expand on this - the error is on line 116 in Icon.lua:

local n = IconDragger.srcicon:GetSettings().UnitConditions.n

UnitConditions is nil. I was able to temporarily resolve the issue locally with this code:

local unitConditions = IconDragger.srcicon:GetSettings().UnitConditions or {}

local n = unitConditions.n or 0

but obviously the actual issue is the missing UnitConditions object

more on this issue - I suspect the issue starts with this error when I first log in:

though I'm also getting this error when logging in (suspect unrelated):

@arieh The second error was indeed the root cause
