Oh good to know, guess gonna have to wait for the update.
I can get you over that bug.
Load your save and open the console in your browser (Ctrl + Shift + I)
paste the following into it and hit enter
SugarCube.State.active.variables.SecretaryActivity.rswipetable = 0;
SugarCube.State.active.variables.ThongsColor = '';
SugarCube.State.active.variables.mcItemWear = ['apron(black)', 'blue thongs', '', ''];
Click the Secretary Desk and it will trigger for you. The next day go into work and "Work a little bit' and you will see the next step in the progression.
If you want to know why that works:
The event can trigger when the secretary asks you to wipe the table and the first line will ensure that happens next time you see her. I think the first problem in the code is that it is checking the ThongsColor variable is empty (this is the bug I think) and your save has it as 'blue' so it needs to be cleared to trigger the event. Lastly, the code checks the 2nd entry in mcItemWear for the thongs color and your save has it as the 1st entry so I swap them to make sure the text shows correctly.
