In most cases we will lock the newer Thread if there is a duplicate, but since it appears you've edited your post on the newer Thread to have more information about your farm, we locked the older one in this case.
As stated above, you can always report if you need us to make changes to a Thread, such as locking a duplicate, or if you need the Thread Title changed, or a prefix added/removed. Only staff are able to make changes like that to Threads.
