Yes, Brock Talon, the WTS is always changing things to suit new developments that make the old "obsolete." I used to ask when the marriage of the bride and Christ would take place. It seemed that if some of anointed lived not die before Armageddon, would they miss the wedding. Also, those individuals were not heaven how could they have a part in destroying the wicked along Christ and the angels (another teaching)?
So now that marriage of the bride will take place shortly after the great tribulation.

“The Lamb’s marriage.” These as a body are called his (prospective) “bride” (Re 21:9); they are promised to him in marriage, and they must be resurrected to the heavens in order to take part in “the marriage of the Lamb.” (2Co 11:2; Re 19:7, 8)

First, the “when” question. Jesus said: “At that time the righteous ones will shine.” The phrase “at that time” evidently refers to the event that Jesus had just mentioned, namely, the ‘pitching of the weeds into the fiery furnace.’ That occurs during the final part of the great tribulation. Thus, the ‘shining brightly’ of the anointed must occur at that future time as well. Second, the “where” question. Jesus said that the righteous ones will ‘shine in the kingdom.’ What does that mean? All faithful anointed ones who are still on earth after the initial part of the great tribulation has passed will already have received their final sealing. Then, as indicated in Jesus’ prophecy about the great tribulation, they will be gathered to heaven. (Matt. 24:31) There they will shine “in the kingdom of their Father,” and shortly after the battle of Armageddon, they will share as Jesus’ joyous bride in “the marriage of the Lamb.”—Rev. 19:6-9.
