To reproduce this issue, follow these steps:

1. Thought > Create Duplicate Child Thought;
2. Edit > Undo "Paste Thoughts";

The duplicate child is removed, but the link is left in the Plex (see the attached image), and I can't activate other thoughts in the Plex. Restarting PB solves the issue.

Confirmed. You can't get out of this by opening another Brain - when I did this, no Thoughts beyond the active Thought were displayed, only links empty at the far end, as in your pic. You have to restart PB. Don't try this command except on a test Brain.
PB on Windows XP, J-1.6.0_17
Dryopithecus, Thanks for the post. I was able to confirm this issue and have noted it for the engineers to look into.

Best regards,
