Triple Triad Challenge: 'Plus' not triggering while under the 'Chaos' rule.

Time: 7 PM (US Central time)
Frequency: Always
World name: Phoenix
Character name: Jeremiah Leroux
NPC name: Helmhart
Monster name: N/A
Class/Level: Summoner(Irrelevant, I think)
Party or solo: Solo
In-game time: 8-10 PM?
Area and coordinates: Eastern Thanalan, 20,21
Steps:
1. Challenged Helmhart to a game of Triple Triad
2. Was set up to perform a PLUS
3. Played a card in a position in which a 'PLUS' should have been triggered, but it was not triggered
4. Played multiple times, and 3 times in a row, I had openings for 'PLUS's, and not once, did it go off.

Proof: http://prntscr.com/8lmk28 <--- A screenshot taken in which my 'PLUS' didn't go off in the game. Placed the Ixali card. 3 + 5 = 8 /// 7 + 1 = 8. This happened with 2 other combinations, and the PLUS merely didn't trigger, resulting in 3 lost games that should have been won. Helmhart plays under the "Chaos" rule. It may be a problem with either Helmhart himself, or the rule "Chaos" in general; unless PLUS' and Same's aren't supposed to trigger under "Chaos".
