The alert for snares will appear again. Previously it was being updated on the snare itself and not the player. It is no longer possible to infinitely ensnare someone; the maximum number is dependent on the target's legs. Only one snare at a time will be removed now. Clarified the wording and logic around CanMoveBreakout. It was inconsistent. Made multiple snares impose cumulative speed penalties. It is no longer possible to remove bolas while moving.
