Possible Giant Spider bug

What you were expecting to happen, and what actually happened?
I cast giant spider, an a giant spider appeared on the opponents team…

What are the steps to make it happen again?
Not sure

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!

You hit the Orbweaver hero with kraken’s trait by casting spider and lining up a match 4/5. Orbweaver can summon a giant spider when they take damage.

Thanks, i checked the troops to see if anything summoned giant spider, didn’t find anything. Didn’t think about checking hero’s even though that is all that was left on the board…
