Nostalrius Begins - Quality wow vanilla realm (1.12)

Anyone else had a problem completing this quest? I got to the lumber mill and turned in the 2nd part but when it comes to triggering the barrel and leave, the barrel becomes unselectable. The crate is still selectable but nothing comes up so i can complete the quest. I tried abandoning the quest and re-accepting it and still not working.

Yes, it is broken. But you can still finish the quest. When you get to this part - you just go turn the quest in to the quest giver. Normally you're supposed to click the barrel and release the termites, then return to the quest giver.
