This isn't the 1st time I've had this problem.

Well just the other day I found a nice spot to harvast some chemicals so I set up some Chemical Harvasters and payed the maint and power for about 1 1/2 days. Today I come back and find that a building just appeared out of no where ON TOP OF MY HARVASTER! My havaster is now buried under the new hill the buildind made and I can't get to it.

All i can see is the very top part going slightly above the ground then sinking back over and over again.

LikeI said this isnt the 1st time this has happened to me and its starting to get annoying. Anyone else had the same problem?
