Broken After 3.8.4 -> 3.9.2 Update

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘ORDER BY form.order ASC’ at line 1]
SELECT form.id AS form_field_id, form.label AS label, data.value AS value, form.type AS type, form.show_on_startpage AS show_on_startpage FROM wp_projectmanager_datasetmeta AS data LEFT JOIN wp_projectmanager_projectmeta AS form ON form.id = data.form_id WHERE data.dataset_id = ORDER BY form.order ASC

Two things where changed when this error occurred.

• Updated from WordPress 3.8.4 -> 3.9.2
• Deleted an entry from the project list

The remaining project entries do show on the page, just this error is above it.

My fault or does this require a fix?
