When using the skill Cubic Seeds for a Duel Links duel, everytime a card is activated or the phase is changed a error shows up (?:-1 : attempt to index a nil value), the effect is not activated and other various errors happen (I had Gueira Guile the Cubic King in hand and couldn’t send a Vijam the Cubic Seed I controlled to the GY to summon it, also I couldn’t use Cubic Dharma effect to discard a cubic card and draw 1).
Bug reproduction steps
Build a full cubic cards duel links deck and play a game.
