Weird Error occurred when saving an article
 

I ran into this error this morning when updating an article. Has anyone encountered this? I recently upgraded to 4.1.9 of vb publishing suite from 4.1.5 vb publishing suite.

vB_Legacy_Forum does not have a field 'lastthreadid' on line 40 in /home5/thrthru1/public_html/vb/legacy/dataobject.php

EDIT: Just found this. Looks like this is a know issue and is due to be fixed in 4.1.10.
