I was unable to find the add new topic button in the Bug Reports forum.
Wordpress: 3.8.1
ACF: 4.3.4
Revisions are created, but the custom field content is not restored when you restore a revision.
Steps to repeat:
1) Add a text field custom field with ACF.
2) Put in some default information in it: 111111
3) Updated it to: 222222
4) Restore the old revision (expected to read: 111111) still reads: 222222
