Originally posted by: rboccuzziIt looks like the node name somehow got a <newline> character put in it, which will corrupt the file. If you want to fix this, you can edit the file directly, and remove the newline before the "==7" (near line 20610), so it goes above, on the line that contains "editor:Label="
If you copy and paste multiple lines of text into the node name, this would cause the corruption you have seen. We have added this detection and prevention in 4.1.6 onward for the 4.1.x branch, and it will also be prevented in 4.5.3 on the new 4.5.x branch.
