0.6.20 Implosion spell not doing damage

OS: Windows 10

Version: 0.6.20

I was noticing that every time one of my creatures cast Implosion, it always did 0 damage. I tested it by manually casting it on an enemy while I had 14k Intelligence to the enemies 3k Defense, and 0 damage was done. The enemy did not have any buffs at the time of casting, but that shouldn’t cause it to do 0 damage, as it is described as being in the small damage category, then damage is increased by the numbers of buffs the target has.
