Fix error due to empty mod_travelnet.data #8

Closed jhcole closed 9 years ago

jhcole commented 9 years ago

minetest.deserialize( data ) is returning nil if data is empty. The result is that the line:

travelnet.targets = minetest.deserialize( data );

causes the travelnet.targets field to be deleted, which then crashes the server as soon as it's indexed into.
