More old-style dropout issues.
I've worn a particular groove into the right drop-out where the nut now likes to sit, but the chain is way too slack there.
I shuffle it back but it keeps slipping back into the groove on impact with potholes or when pulling Wicked-Cool skids.

I probably shouldn't have overtightened to create the groove in the first place, but is there a solution? File it down and start over?

I've got the same CSB - I've noticed that this weekend.

I've been over-tightetening too.

New chain? Half link chain?

I think that'll work
