it has been there for ages. lots of requests to change it have been posted as well. will we see a better solution in FZ 9?
if at least in the meantime we would get the information what the objects name was and on which layer it was deleted...
one solution to this would be if FZ would create a special 'quarantine' read only layer where it moves these objects, so we can examine what objects went wrong. this layer can then be purged when not useful anymore.
even better, fix the reason why this happens at all. if an object is corrupted by some operation, it should be reported immediately to the user whth an option to undo the last operation.
