So from what I understand and the fix that worked for me current  patch 4'th Jan 2024 is, that the texture files for the ready check ticks and what not have changed to this. First line {1'st}{2'nd}{3'rd} is the original and second {Fix} is the replacement, it's a text edit for 3 lines from the addon files so presumably an update would fix this. Taken from Hollo6 on https://legacy.curseforge.com/wow/addons/shadowed-unit-frames/issues/1995

In-case anyone finds this and is wanting more detail, the file you need to change is in your '_retail_\Interface\AddOns\ShadowedUnitFrames\modules' Folder and called 'indicators.lua'. Hope this helps someone =]

Also I haven't tested this in anything other than retail so not sure if the same changes apply. But if you don't have the ticks, I can't see it hurting at all ^^

They changed the textures for the ready check icons.

To get them back, change the following in modules/indicators.lua:

{1'st} frame.indicators.ready:SetTexture(READY_CHECK_READY_TEXTURE)

->

{Fix} frame.indicators.ready:SetTexture("Interface\\RaidFrame\\ReadyCheck-Ready")

{2'nd} frame.indicators.ready:SetTexture(READY_CHECK_NOT_READY_TEXTURE)

->

{Fix} frame.indicators.ready:SetTexture("Interface\\RaidFrame\\ReadyCheck-NotReady")

{3'rd} frame.indicators.ready:SetTexture(READY_CHECK_WAITING_TEXTURE)

->

{Fix} frame.indicators.ready:SetTexture("Interface\\RaidFrame\\ReadyCheck-Waiting")

Without this the ready check ticks do not show up, at least for me this seems to fix it all =]
