how ccould that happen
if you place a Beacon there is automaticly created a location in your Location Tab
so if you build 2 warp conduit you usualy should be able to chose your home location
i think its impossible to delete your home location
if it IS possible to delete it open a support thread with this story and suggest
an automatic add of your last location befor entering the warp portal as a funtion for future releases
or add it here
