I got the following problem This is the initial evaluation order of activities computed by FET. If the generation gets stuck after a certain number of activities, please check the activity corresponding to this number+1. You might find errors in your input.
Please team how can i fix it
This is a normal problem for difficult/impossible timetables, when you interrupt the generation.
You might want to attach your fet file here, so we can have a look, or send it to me by email if it is private.
