Any puzzle whether (a) in lab, (b) on ANY development server, or © anywhere in eterna that does NOT autosave should post some obvious alert/warning on it so players know to revert to saving progress via screenshot and export of sequence to text file (so we do not lose our work).
I, for one, no longer screenshot every solution like we used to do when (a) auto-save was buggy, (b) server did not give you your solve, and © we lost stuff when eterna_development_team changed servers. But, now, things are so much better [HURRAY] with (a) consistent autosave working, solves available from the eterna server, we have been we are trained to expect auto-save.
But autosave is not present consistently across eterna’s many interfaces.
A low cost, helpful, and hopefully easy change.
