Big/issue completing actions

Hi there! I am trying to complete the Journey to Midwest and Clover Cottage and when my sims are about to finish an action they just stop doing it. I don’t understand why this happens, but as a consequence I have to restart the actions again (some actions last 15 hours💔 ) and I fall behind and loose the prices. This is the third time it happens to me since the last update on March 13. I have an iOS.

thank you for your time!
