Duration text disappeared for some random aura buttons

[Layback_]

Hi,

This thread is somewhat related to a thread here.

I've been implementing auras element to my UI and found some strange bug(?) which also happens on my other addon as it is shown a thread above.

Basically I haven't touched anything apart from buffs and debuffs frame creation, and am using default aura button creation provided by oUF.

function GenerateBuffs(frame, unit)
    local buffs = CreateFrame("Frame", "$parentBuffs", frame);
    buffs:SetPoint("BOTTOMLEFT", frame, "TOPLEFT", 0, 25);
    buffs:SetSize((ICON_SIZE + 1) * (ICON_PER_ROW - 1) + ICON_SIZE, (ICON_SIZE + 1) * (ICON_PER_COL - 1) + ICON_SIZE);
 
    buffs.size = ICON_SIZE;
    buffs.spacing = 1;
    buffs.num = ICON_PER_ROW * ICON_PER_COL;
 
    return buffs;
end
 
function GenerateDebuffs(frame, unit)
    local debuffs = CreateFrame("Frame", "$parentDebuffs", frame);
    debuffs:SetPoint("BOTTOMRIGHT", frame, "TOPRIGHT", 0, 25);
    debuffs:SetSize((ICON_SIZE + 1) * (ICON_PER_ROW - 1) + ICON_SIZE, (ICON_SIZE + 1) * (ICON_PER_COL - 1) + ICON_SIZE);
 
    debuffs.size = ICON_SIZE;
    debuffs.spacing = 1;
    debuffs.num = ICON_PER_ROW * ICON_PER_COL;
    debuffs["growth-x"] = "LEFT";
    debuffs.initialAnchor = "BOTTOMRIGHT";
 
    return debuffs;
end

However, for some random aura buttons, it starts to not show duration (cooldown text, cd:GetRegions()) as it is shown below.



At least I tested it on Rogue, Druid and Death Hunter, but they all had a same issue.

Unfortunately, this is sooooooooooooo random and I can't really think of the process to re-produce this issue.

I'm currently thinking that this would be an internal Lua bug with Blizzard's code, but who knows
