[Ulduar 10 man] Ingis the furnace master's iron construct won't become brittle

[crittycat-dalaran]

Current behaviour: Every Iron construct AFTER the first construct is killed will no longer become brittle when moved into the water with 10 stacks of Heat.

Expected behaviour: Every construct that is Molten after 10 stacks of heat should turn brittle once it touches the water.

Steps to reproduce the problem:

1. Root first construct into fire, wait for 10 stacks, run it into water, it becomes brittle and is destroyed by a raid member.
2. Root the second construct into fire, wait for 10 stacks, run it into water, It stays on the edge of the water and does not become brittle.
3. Root the third construct into fire, wait for 10 stacks, run it into water, It stays on the edge of the water and does not become brittle.

Iron Construct - Iron Constructs brought to ground scorched by Scorch, will gain stackable Heat buff, which increases their movement speed and haste by 5 per application. If Iron Constructs gain 10 stacks of Heat, they will become Molten, increasing their haste by 100% and inflicting 1,885 to 2,115 Fire damage every 1 second to enemies within 7 yards. Molten Iron Constructs can be brought to water, which causes them to become Brittle and unable to perform any action for 20 seconds. Critical strike chance against Brittle Iron Constructs is increased by 50%. If a single attack deals more than 5,000 damage to a Brittle Iron Construct, it will Shatter, inflicting 18,850 to 21,150 Physical damage not mitigated by armor, to enemies within 10 yards. Shattering the Construct causes Ignis to lose a stack of Strength of the Creator.

Hello there,

Thank you for the report, doing some tests at the moment but I do not seem able to reproduce it, works fine on every test. Could you please provide a video if this happens again?

Sometimes there is a specific condition ingame on a "real raid" environment that might trigger the issue, this way I could try to see if there is something wrong.

I will see if it happens again, I had another hypothesis that it might be that only one construct can become brittle if multiple are alive.
