Not that good example video, but i guess it's better than nothing, basically... it won't always complete it's task given, not espesially on the other side cus there is much more space and they're free to move on larger areas. Kinda like stops the half way when the Mound is moving away from you or stops near to it and does nothing. There's no problem if it's moving towards you, almost always works in that case.

Next update will contain a fix, thanks.
