Life bug

I dont know how it works situation: i had 1 ripper carry and 2 miss jillys and between them a dungeon door makes goblin every 3min and one of the jillys had the skull of darkness problem: when a goblin was spawned from the dungeon one of 3 towers killed it (other towers are so weak to kil there was no creep waiting for next round but my life decreased 2% without leaking

oh i just found the reason as i reported when just spawned goblin hit by withered set and time warped the goblin moves like teleport and sometimes it sends the goblin to finish line
