On GPS, the goal was to send post-accelerated 226Rn beams to a traveling setup on the third HIE-ISOLDE beam line to study fission barrier heights in exotic neutron-rich nuclei. After the issues with the production of the beam from several targets, it was decided to go to a different isotope 226Fr still allowing to study the same physics case. Despite problems and last minute change of plans, the beam could be delivered still on Friday evening and the experiment went finally relatively smooth with good data obtained. It was a major effort by the machine supervisors and the target team, who ensured that the experiment could still go ahead. Their dedication was greatly appreciated by the users, and it truly highlights how fortunate ISOLDE is to have such a knowledgeable and committed team.
