The GetCategories call is sometimes returning version 49 (old version) and sometimes returning version 50 (new version) of the eBay US Site.

When data publishes are made for categories or attribute metadata, the application servers pick up the publish when their caches are refreshed. There are times where some machines are delayed in picking up the data publish due to operational issues. Unfortunately these situations lead to the inconsistencies in metadata versions where calls return different versions due to the different cached data of the application servers. When these situations do occur, the delays between machines are usually an hour at most due to the sheer amount of time it takes to refresh the caches on all of the different application servers.

If you do get varying versions, always save and use the highest version number.
