TokenAction.newTurn throws "TypeError: Cannot read properties of undefined"

To recreate this bug:

Select three tokens on a map.
Right-click and Toggle Combat State.
Open Combat Tracker and roll initiative for all combatants.
Begin Combat.
Click the Next Turn arrow until you reach the last token.
Click Next turn -- error occurs.

The error is thrown on line 610:

    // Check for Effects marked for this turn
    const effects = this.lastManeuvers[Math.max(round - 1, 0)].nextTurnEffects || []
    for (const effect of effects) {
      await this.token.setEffectActive(effect, true)
    }

At this point, the "lastManeuvers" collection looks like this:

The other combatant's lastManeuver looks like this:

If it matters, I have the following system settings:

• Use Foundry Items = false.
• Show Confirmation Dialog = False
• Allow Roll based on Maneuver, Check for Targets before Roll, Allow Action after Max Actions = "warn"
