I have been able to repeatedly duplicate the quantum tank from QuantumStorage by shift+right-clicking it while it is next to an ender lily from Extra Utilities 2 while the lily is at approximately 50% growth. This is a really awesome bug cause, free stuff is cool, but I thought that it should be brought to the attention of people. Hopefully other folks can replicate this cause if I'm the only one dealing with having to trash god knows how many quantum tanks then I'm going to have a sad. Ps. It seems to duplicate the tank on the side you click it, as a world item.
