+** CLOSED History loops <2019-11-08 Fri>
+
+Occasionally elpher gets stuck in a "history loop" where a
+node is its own grandparent. Obviously this sucks, as history
+is elpher's main mechanism for making gopherspace exploration
+painless.
+
+I suspect the problem is in either ~elpher-visit-node~ or
+~elpher-visit-parent~.
+
+Follow-up: this has been fixed by the new stack-based history system
+in 2.5.
