There seems to be an occasional bug when my Firewound Angel attacks. Most of the time it is normal, but occasionally the attack does damage that shows two decimal places ( so “you deal 180.53 damage”). It doesn’t seem like this does any actual damage to the enemy creature. It doesn’t activate enemy “when hit” abilities like invisibility for a Willow Spirit. I have also never seen it alter the damage status of the enemy creatures (so badly always stays badly, somewhat stays somewhat etc.). I am playing on iOS, with version 1.3.0.
I would estimate this happens maybe 25% of the time at most probably less! and I can’t say I have found any underlying cause for when it happens.
