You can stop it happening by dot punching the back of the sprocket in three or four places around each cush drive. Get the dots right up to the edge of the bore. This'll indent the bore so the outer sleeve of the cush' cant come through.
You'll need to replace the cush drives, but if the sprocket is OK then keep it until it's worn out. You could then think of a Renthal or similar type carrier.
Providing the wear isn't too great on the hub, you'll be OK. Clean it up when you remove the sprocket carrier.
If you've worn it through to a point where the castellations have all but disappeared and you can't get a C-Spanner on them to adjust the chain you'll need to replace the hub.
