Hello all,

Today I noticed my low-e string was very very close to the fretboard on the first 2 or 3 frets. How can this be ?
When I play a chord, it's like there's no string under my finger, I can barely feel it!

I checked if my nut was cracked, but I see no visible mark. I don't undestand how my nut could have got that low overnight ? The other strings seem OK.

The nut is a good quality bone nut I bought on ebay, and has been properly filled by a pro about more than a year ago. It's the first time I have a problem like this...

Is my nut simply "worn out" ? Should I buy a new one?

The guitar was setup by a pro in july, the action was set quite low for the best playbility. Not amazingly low, but you know, a "normal" action
What kind if guitar is it? Checked bridge saddles?
ich bin indeed ein sprechender panda, how are you?

It's a les paul custom, the bridge has not changed (since the other strings are OK)
Your neck probably straightened out some and needs to be adjusted. It happens.
