SO, there is that little lock icon which works to lock a thread but how can I unlock a thread once locked?  I only see the "lock" thread icon and clicking it again after the thread is locked doesn't have any effect. 

Has this been happening since the update ?, as the lock icon is the right button to click to lock or unlock a post.

I have noticed that sticky's and locking will not show up on the page when done (since update) even when refreshing the page, logging out and back in usualy helps to bring back the icons. think its a bug from the new update.

Hope this helps.

Hey guys, patch has just been released. Please check again! Thanks.
