RE: [Repast-interest] Grid issue with value display in space

Hi Trushar,
I think, I've replicated your problem and then solved it.
(I was using the version of your project I fixed last time.)
The problem seems to be that your GameSpace extends Diffuse2D.
Are you sure you want your values to change on their own?
In any case, replacing that wirh Object2DTorus solved the problem.
I hope this helps.
