Sims 1 Legacy BUG - Gardener not showing up, plants dying

I've encountered a bug where I've hired a gardener but the gardener just randomly stops showing up. I've attached a screenshot showing that I cannot call the Gardener (or maid) because I've already hired them. My flowers and plants are dying because they are not being watered. I cannot fire and rehire the gardener as I cannot call them and they do not show up to be spoken to in person. I also noticed this happened once with the Maid but she showed up after a few days.
