I went through your post too fast, I missed the bit about the semi-rare.
If we go back to the log, though:

[113655] Barrel Full of Barrels
Encounter: Barrel Smash
You acquire an item: bottle of whiskey
The semirare is definitively a determining factor.
What was supposed to happen during "Request 8 of 140" was:
- notice the semirare counter is up, call the counterscript (which adventures in the Haunted Pantry)
- execute the original request of adventuring in the barrels
What happened during "Request 8 of 140" is:
- notice the semirare counter is up, call the counterscript (which adventures in the Haunted Pantry)
- "No location selected." error
The "No location selected" error explains why a square was missed, but I don't really see why it happens, if it's not the semi-rare.
Actually, I don' really see why it happens even if it's the semi-rare.
