I've "felt" it 2 weeks ago. I've only "found" it now.
No one entered your reed farm, it was entirely closed off.

Your engines were pulling your Density Gems and Blackhole Bands out of the chests and through the pipes (to where they had no effect and caused all of the reeds to pile onto the ground.)

That, and for about almost a month now we've been bitching about the constant lag and crashings due to said reed farms. You know, the same constant lag and crashings in the past two weeks that made everyone leave.

They anything like your last two friends that went and wrecked a town and stole everyone's things?
