If your report is about a missing or wrong spell provide the following information:

• Your class: Demon Hunter
• Your spec: Vengeance
• Name of the spell (and spell id if known): Sigil of Flame (204596 / 204513 with talent / target dot 204598)
• Source of the spell (core ability/talent/pvp): Core / talent modified
• Do you use a macro to cast the spell (post the macro if so): No

If you have an error report, copy it below:

I'm not seeing an error but I was able to get it working with a user rule:
return Configure {
"Sigil of Flame",
"Show Debuff when Enemy is affected by Sigil of Flame",
{
204596, -- Sigil of Flame (Vengeance)
204513, -- Sigil of Flame (with Concentrated Sigils talent)
},
"target",
{ "UNIT_AURA" },
function(_, model)
local found, _, expiration = GetDebuff('target', 204598)
if found then
model.expiration = expiration
model.highlight = 'bad'
end
end
}

Thanks for the report. Will be fixed in the next release.
