Having an issue with object caching. Set a 1.3MB object into the APC cache, and I'm seeing it in there fine with the APC explorer. However, for some reason on line 72 of Apc.php (W3_Cache_Apc) the _get_key_version() for the group is *always* returning 1 higher than the stored $v['key_version'].
Because of this, the cache is resetting after every single request. What reason would there be fore the version being so out of sync, and what can I do about it?
