This may seem like the old Time Travel glitches at first. But the effects are a bit different. It is now possible to visit the 3rd tower if you Time Travel from the beginning. In the past, the only way to Time Travel to the 3rd tower was to start from the 3rd Rally Point. But now, when you Time Travel from Mission Start, you can still get to the 3rd tower and even go inside. Inside the 3rd tower after Time Traveling is a semi secret switch.
