Generation halting at 11/71 activities

[laura]

Hello,

I am quite new to using FET having recently discovered it. Thank you for creating this software, it has been a game changer for us!
Our timetable is not as complex as others I don't think, but when I have all constraints active it stops generating and does not progress. It is not always the same activity causing problems. I am sure I am probably doing something quite obviously wrong. we are working with a manually written draft of the timetable alongside FET but hope to move fully to FET next term when our schedule is more complex. We started with a file which generated a timetable meeting almost all of our needs but it fails to generate with more constraints added. I am attaching both versions here in the hope that you can help to identify the issue.

Hello, laura,

I unlocked your impossible file. I removed and removed until I obtained a minimum impossible file. Please see the highest-stage partial timetable in the screenshot, and the remaining time constraints (the space constraints are negligible), and analyze why it is impossible. I think you will recognize the impossibility better than me.

Please let me know.

Thank you - I will take a look at your file!
