Opponent Code has an error, I cannot move: Error: "You can't use Hero Placeholder 1's `attack` method here."

Error: You can't use Hero Placeholder 1's attack method here.
These are the players from the Top 20 of the Red leaderboard:

  • jasoneilif
  • turnaround
  • Deadpool198
  • JustALuke
  • DimaP
  • Jason Lin5

Can we please check?
You can reproduce by challenging them with this “do nothing” JS code:

var i = 0;
while (true) {

Expected, I get log statement that counts up to the limit.
Actual: For most of these players I get around 10 numbers logged.
