Printing defects with Using Castable Wax Resin

Good all the time. After finding the resin for more than a month in the bath, when printing every three days, trouble appeared, the details lost accuracy and no uniformity was visible in the surface. Well visible artifacts on the substrate of the model. What is the reason for this? degraded the bottom of the bath or resin loses its properties? https://ibb.co/sFn7Jdj
