I cannot get rid of this cold. However, the symptom is finally getting better.
When I logged in to SL after an interval of three days, some of my horses were tormented by hunger. I must supply them with food first.
And one horse suffered from a disease in the worst thing. The cause is that choice of food of the horse is changed without permission. Though I do not change the setting of the horse, the setting changes. In most cases, as for them, setting of food is changed without permission. I think the phenomenon to be a bug.
I feel exasperating that I purchase a healing kit for recovery.
