337 'Revenge of the Rot!'
Removes 304
Rot's initially in one random Cell.
At each Move's start, Rot-unaffected Cells adjacent to one Rot Cell develop Rot, and Rot Cells adjacent to one or two Rot Cells lose their Rot (unless this'd result in no Rot existing).
If a non-immune Player shares a Cell with Rot their Orange count becomes 0.
A Player can - if they've not had immunity in the past two Moves - buy immunity for 10*n Oranges, which lasts until n Moves after the end of the current Move.
In Rule 336, “, unless they've immunity: 1;” is removed and “Orange-Rot: 2” is replaced with “Rot: 1”, then this sentence's removed from this Rule.
