Bug. I forgot to add this feature back when implementing chunks in chunks.
I just adjusted this in 1.88 (which is still in beta).
Please note that in the new version you will use the mumamo-chunk coloring number. Set this to 1 to avoid coloring the blocks in the main mode, etc.
By the way: It just happened. If you want to fix errors, it is usually best to report them to the nXhtml error database on Launchpad.
