Humor in Heroes of Might and Magic V.

I don't know if this is a bug: when defending an Elven castle, the enemy enters the moat, gets entangled in roots, and on the next turn, the roots disappear, and the enemy can move. Moreover, the roots disappear, not "untangle."... I haven't experienced this (when I accidentally entered the moat).
And another bug: if an entangled enemy in the Elven moat is killed, the enemy dies, but the roots remain...
