I've not come across locations being unset.

If "deleting a tape index" you are selecting a volume on the volumes 
window and then deleting it, then the behaviour your seeing is correct. 
Networker has removed all idea of that tape from the current view to 
reinstate it you will need to inventory it. If you are using a direct 
attached SCSI library then there will be a slot with a "-" in it just 
inventory that slot. If you are using a silo then inventory the volume 
name you just removed.

We use recylce to/from pools on all pools (and when using 6 even the 
default pool! ) and don't see this causing problems.
