Bubble coral with exposed skeleton temperature related?

[Tennyson]

Hey everyone, so I bought this massive bubble colony while on vacation and drove it 12 hrs home. It had flatworms so I dipped. Had some damage to the skeleton from shipping, and even more damage after dipping. Overall though it was extending beautifully the first two days.

On day 3 I left a window open and my tank dropped to 65F overnight. Was shocked to see my bubble with tons of lacerations on the skeleton. Do you think this is just the damage from before that's reopened or new damage?

I'm surprised at how thin the tissue is. It seems like the cold made it shrink up so tightly that it tore onto itself. Like I said even a dip caused tissue to tear. anything I can do to fix it?

Has it improved any over the past 2 1/2 days since you posted?

Yes all is well now, put my heater in to prevent any cold temps. Just surprised the cold did that much damage.

Here it is today

I recently noticed a similar laceration in bubble coral tissue (with skeleton exposed) prolly from high flow as nothing touches this coral (most potent in the Lps tank). Will give it time and see what happens.
Thanks
