[Gramps-users] Places references

[Chuck A. <cc...@de...>]

I'm using v 3.3.1-1 with Linux Mint 9
Somehow almost all of my "Places" have lost their references-- not, however, in all cases but in most. The ones that seem ok are where the reference is an event.  I have tried the "Place completion tool" but either it doesn't do the job or I'm not using it properly. Any idea what would cause this and how do I restore the references?
