Hi, glad things are not as bad as they could have been.
It would be a good idea to inspect your glass periodically for mould though, especially after a spell of damp weather - bellows and other parts can hold countless spores and they could affect any of your lenses from now on. Catching it early is crucial.
Your repairer will have treated what he could reach with fungicide but it just isn't possible to cover everywhere spores can settle.
It's good policy to check your glass frequently anyway - even without a dunking - spores are all around us, all the time, just waiting to get you.
Don't have nightmares...
And Happy Holidays!
