I believe it was fixed in 3.6, but 3.6 is not stable yet.

MySQL Error : Unknown column 'hhroptions' in 'field list'

I am not sure why it's not in XML, but please run this query:
[SQL]ALTER TABLE PFXusergroup ADD hhroptions INT UNSIGNED DEFAULT '0' NOT NULL[/SQl]

Replace PFX with your table prefix.
