Firewound angel bug

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.

Thanks for letting me know!
