28mm Summilux-M focusing ring dead spot

Wondering if other 28 Lux owners have come across this problem: play in the focusing ring that results in a 'dead spot' when switching focus direction. 

 

My copy of the lens currently has about 3mm play where I can move the focusing ring left-right, in the focusing directions, but it does not result in any change of focus (doesn't engage the helicoid). The ring feels entirely disconnected before it pushes against something underneath it. If I keep turning the ring once it 'engages' it then changes the focus as it should. It also moves freely in the north-south directions (if focusing is east-west). Recently I noticed a faint rattling sound of something like a loose small screw or ball bearing when changing the orientation of the lens.

 

This happened all within the span of about a day a little while ago and have kept using the lens, in part due to reluctance to be without it for up to two months for servicing. Initially it was a very slight wobble that was annoying enough on its own, but quickly got much worse with the much greater and more annoying dead spot, as mentioned, of about 3mm.

 

While I'm not the gentlest with my gear, I don't recall any specific incident that may have damaged the lens. I'm the second owner of this copy, received in nearly mint condition back in June 2016, and have used it fairly regularly since then. I thought it might be bad luck but this has now also happened to a friend's copy (that I have not touched :) ), which seems too coincidental...

I'm not expecting this will be a widespread problem since I haven't read any complaints about it before, but wanted to mention it since there are at least two of us with this problem occurring within about a month. Perhaps it's something that will start to appear after longer term use for some.

I have the 35mm Summilux ASPH FLE, and it, suddenly, did exactly the same thing. Probably about seven or eight millimetres of play. Quite annoying on a very expensive lens. I'll just have to live with it until I can afford to have it serviced.
