not a problem. you want to use 0 most of the time when creating instances.
unless you've done some heavy customization, there should only be 3 zones with other versions numbers in your database.
Code:
select zoneidnumber, version, long_name from zone where version > 0;
+--------------+---------+---------------------+
| zoneidnumber | version | long_name |
+--------------+---------+---------------------+
| 25 | 1 | The Nektulos Forest |
| 151 | 1 | The Bazaar |
| 114 | 1 | Skyshrine |
+--------------+---------+---------------------+
