Getting voice msg, saying Passing Thermal layer

[billk1]

I am on the Guam Insertion campaign, have TMO 2.5 loaded.
While on the surface in route to Guam I keep getting a voice msg saying,"Passing thermal Layer". I though you only get this msg when submerged, any ideas as to what is wrong.

the game has glitches witgh tghings like that at times, the way to "reset" it is go deep then resurface. that should restore the correct timing of the message.

Thanks Webster for your reple, I will give it a try.
