I was under the impression that players can use evade tokens to cancel Ten Numb's crits, since they're not dice, but after searching the FAQ for more information, I found this recent update on Autoblaster, which is worded identically to Ten Numb.
The defender cannot cancel [hit] results with evade tokens or other added [evade] results, such as from C-3PO, when attacked with Autoblaster (see “Dice Results” on page 8).
And this this update on Dice Results:
Dice Results Results that are added are treated as dice results that can only be canceled (they cannot be modified or rerolled). For example, when attacking with “Autoblaster” a [evade] result added by an evade token cannot cancel a [hit] result.
So does this mean that evade tokens, C-3P0 and Autothrusters cannot cancel Ten Numb's crit rolls, and is this a change to how the rules were being played before? Thanks.
