I'm not sure this qualifies as an actual bug, but it certainly runs contrary to expectations and doesn't seem like something that should be able to happen. http://www.flickr.com/photos/51205520@N03/10303874386/lightbox/ In the screenshot you can see that Tesla the Lightning Sprite is standing around the corner and doesn't have line of sight on Lavender the Elf Warrior. Nevertheless, it hit Lavender with a Lightning Bolt, as you can see from the battle log. I can understand Bursts exploding around corners because they originate from a space that is in line of sight, but it doesn't seem like Lines should be able to bend around corners.
Lightning Bolt has a Linear effect that allows attacks on tiles not in the line of sight of the caster. Only cards with the Burst and Linear keywords have such capabilities. http://wiki.cardhuntria.com/wiki/Combat#Using_area_of_effect_attacks Hope it helps.
You was hit by this Lightning Bolt which is a linear attack, so it can hit you without line of sight. From the wiki:
