AFAIK the fix is to have a service (or multiple) stay online for you, and I believe it could be done without requiring access to your private keys. If your counterparty broadcasts a stale transaction that's in their favor, your service will broadcast a newer transaction that reverts it.
Haviong trouble finding it now, but google "lightning network routing problems" and you'll get a lot of results. IIRC the fundamental issue boils down to a hard mathematical problem about node traversal that is not yet solved. I am having trouble recalling the name right now, apologies.

There have been ways that a counterparty can close a channel in their favour if you aren't online. Perhaps this has been fixed by now.
