buildpyramids with Daggerrunner gives random result

[felixcremer]

using buildpyramids with a DaggerRunner gives a random looking result.
It seems as if the chunks are not saved correctly but more or less randomly.

Now that I am using colorrange for the plotting I see, that the result is not fully random, but there are some chunks which have way to high values.

With the localrunner this does not appear.
