Shadowtouched Kvaldir effect not taking place

Duels game with Elise, the order of cards I played:
Funnel Cake
Shadowtouched Kvaldir
(Hero power for armor)
Frost Lotus Seedling
(Attack with minion)
Tree Of Life.

There were no healing effects between Kvaldir and Tree Of Life, yet it was used for healing.

Did the minion have lifesteal or some other similar effect?

i had bug with same card attacked with truesilver champion then played sunspot dragon, dragon damaged my face

No, it was a treant with no keywords. I intended to post a screenshot but it didn’t let me

you have to post the screenshoot link using Preformatted text </> button on top of text editor , so link became unclickable but we can see it.

edit: it’s possible you selected the duel passive threasure that heals after nature is casted , Frost lotus Seedling is nature .

undefined · Spell · undefined · Passive After you cast your first Nature spell in a turn, restore 2 Health to all friendly characters.

mb some other passive treasure but i cant think other ones.
