"CancelError()" is blocking the tree live processing

Created by: rendetto

This error occurred when I tried to Live Update a tree. The same tree is processed without problems when animated. The tree was running with no errors with the previous update system.

The other weird thing is that this error appears very erratic and on different nodes. Is that normal? For example the next time I executed Live Update the left node didn't throw an error or red color, but the tree sill doesn't update. Here on another run of the Live Update I got this(tree still doesn't update):

I'm also a bit lost with those flashing colors of the nodes. What means red flashing and what green flashing? Why are those errors and how I have to read this info so I can debug the problems? Thanks
