Ok in the midst of World War Roo and the Great Roo-pression of 2011 and long food lines, I have another problem, small but infuriating.

I have about 10 stumps and it looks like ALL my roos have stump hopped overnight. All my carefully arranged generational/trait pairs are now all over the place.

Did they have an orgy last night and those are the stumps they passed out next to?

I'm afraid to move them back due to all the disruptions lately.

Is this due to those or is this something roos "just do" from time to time?
