This is common with overwatering. This can lead to an infection which will cause sudden wilting. You will have to replace the soil, and I also recommend only watering when the top few inches of soil are completely dry.
I would also suggest for the next time that you water, to mix peroxide at 1 part to three parts water. Or just replace 1/4 of the water with peroxide. This will help kill off any remaining infection in the roots.
Cut the growth off when it dies, and let it come back again.
