This was originally a bug that players were capable of exploiting before cards played from hand had a delay function. A player would play all towers, pillars, and pendulums in hand. Pillars and unupgraded pendulums (those that should not produce extra quantum when initially played) that were played after a tower or upgraded pendulum would also activate the extra quantum ability if they were chained in rapid succession. Now with the new high speed AI, this bug is re-exploited by the fact that they do not have such delay. Not much of a problem with AI5, though it can be a little unfair at such a major start. The major problem is PvPing with semi-upgraded decks for whatever reason, this bug would then probably cause a desynch error.
