2D slice shows up as red blotches

When loading a new cube, the 2D slice very rarely shows up like shown below. Scrolling to another slice doesn’t help (the picture changes, but it’s still red). Clicking on it to color some part reverts to the usual b/w picture and fixes the problem.


Same here. Just before this happened, after points for the previous cell were awarded and before the new cell showed up, I accidentally clicked in the 2D view of the old cell, coloring a section.

Oh I’ve gotten this too!  Creepy looking isn’t it?  This is a bug.  For me if I clicked in the 2D it fixed the problem.  If that doesn’t do it, try refreshing the page or hitting ‘skip cube’
