Just got in and was checking the tank. Lights on full schedule and noticed my full tilt favia looked different. Had a soft jiggly mass on the right. Idk nothing new or different. System just doing its thing.

I don't know if this is related or not, but it reminds me of when corals "bounce" unexpectedly (such as the acans discussed below):
So, it may be high lighting/UV or it may be elevated potassium; I've also heard of this happening to a number of other LPS corals (including different hammers), with suspected potential causes such as: coral starvation/lack of nutrients in tank, coral overfeeding, lack of flow, and toxins and/or activated carbon. No one seems to know for certain what causes it, though, and it doesn't seem to be harmful.They're basically joking that you've either got two corals or a "bounce" acan that would be potentially be valuable.
The only thing I can find on this condition is that it may potentially be caused either by some kind of high lighting (some people say LED's, others UV; it's basically thought to be similar to sunburn reaction in people) or by elevated potassium levels, and it doesn't seem to negatively impact the corals in any way (but the bubbles if popped are prone to infection):
