Make sure you apply all of the sql updates that are newer than your database version. I'm not sure where they are located when you use a precompiled server version, but if you use SVN they are in the trunk\EQEmuServer\utils\sql\svn directory.
The one that I believe fixed this problem for me is 1618_zone.sql, but there are a couple of others too.
Code:
ALTER TABLE zone ADD suspendbuffs tinyint(1) unsigned NOT NULL DEFAULT 0;
UPDATE zone SET suspendbuffs = 1 WHERE short_name IN ('guildlobby', 'guildhall');
