Order 66 Bugged

Location: Squad Arena
Enemy Team. Lord Vader, Appo, GI, Reva, Royal Guard with Appo bespoke Cron
My Team: Leia Organa, Drogan, R2, Capt Rex and Old Ben

My standard approach is to use Drogan to snipe out Appo, then GI and kill Kmightfall Trooper asap

The bespoke Appo datacron reads: 

If the allied Leader is Lord Vader and all other allies are Empire, the conditions requiring all other allies to be Dark Side Clone Troopers for CC-1119 "Appo"'s Vader's Fist Unique ability are considered met.

Whenever an enemy dispels any amount of Damage Over Time, CC-1119 "Appo" gains a stack of Operation Knightfall for each enemy that had a stack of Damage Over Time dispelled, and he inflicts Order 66 on a random enemy that had a stack of Damage Over Time dispelled, for 1 turn, which can't be copied, dispelled, evaded, or resisted. At the start of each Dark Side Clone Trooper's turn, all allies gain 10% Defense Penetration (stacking) and Offense (stacking) for 1 turn for each stack of Operation Knightfall on CC-1119 "Appo".

However this is still applying when Appo is dead and Order 66 is being applied to a random enemy that had DoT applied.

How to duplicate: Use teams and Appo datacron you will be able to recreate this easily as it happens every battle in Squad Arena. I have not been able to test in Grand Arena
