I've just tried upgrading my forum to 3.8.4. I had this installed already (v1.0.1) and I get a DB error about a duplicate column.

Database error in vBulletin 3.8.4:

Invalid SQL:

	ALTER TABLE vb3_thread
	ADD sticky_order SMALLINT( 5 ) UNSIGNED DEFAULT '5' NOT NULL AFTER sticky,
	ADD sticky_expiry INT( 10 ) UNSIGNED DEFAULT '0' NOT NULL AFTER sticky_order;

MySQL Error   : Duplicate column name 'sticky_order'
Error Number  : 1060

How can I fix this without having to set up all my stickies again?
