[Con] Memory leak when creating large farms

I have not noticed this again since the new release. I think it’s been resolved! See for example 7:33, 12:54 in the below video.

Something similar happened to a lesser extent near the end of the video (noticeable almost only by looking at the debug information, really), e.g. at 50:29. Not sure if related, although not via farms I think (I had two big’uns, but they were unmanned at the time).
