Been wondering for some time so today when I played vs a Viktor, I paid attention.

Elementalis vs AI Viktor Campaign 1-8 between 9 AM and 9:30 AM EST today 9-9-2020

Elementalis Turn 5 - my Stardust Ampliflyer gets caught in 1 of 2 Net Traps AI Viktor had out. I presume this counts as one of the three turns mentioned on the Trap it will be disabled.

Elementalis Turn 6 - I check my disabled Apliflyer, it still shows 3 turns of disabled when I expect it to be 2.

I think Net Trap is bugged to not count the turn it applies the disabled on target. Other cards like Poison Arrow, Freezing Grip, etc. do not do this, they count the turn Crowd Control is applied.
