Im pretty sure this leaks, need fixing

[Marsunpaisti]

So, the point of this spell is, that the hero burrows underground, then it spawns a rally point modeled unit for you to "symbol" where the burrower would be underground. Then it saves a point ever 0.5 seconds and when burrower surfaces, in the locations an impale spike effect appears and does damage.
But the fixing here is that im pretty sure this leaks and i want them fixed.
