When a Poder Keg explodes current unit lost its turn?

[Vilk]

Weird I never quote that, when a Powder Keg explodes the current unit losts its turn. For example if I make it explodes with a spirit or a spell my current unit lost its turn for this round.

I'm used to use Evil Shoal to get rid of such stuff and I'd be surprised to not have quote it yet. But well I do that more rarely with those items.

I reloaded the game and even restarted my computer but still has this behavior in a ship pirate fight.
