Too many lessons are assigned to this room — it cannot accommodate them all.

What causes this error

The total number of lessons assigned to this room exceeds the number of available time slots. A room can only host one lesson per time slot.

This typically happens when too many lessons have a restriction forcing them to use only this specific room.

How to fix it

1. Distribute lessons across more rooms — Review room restrictions on lessons forced to use this room and allow them to use alternatives.
2. Add more rooms — If this room is genuinely the only suitable option, add additional equivalent rooms.
3. Remove specific room requirements — Remove the room restriction from some lessons and let the scheduler choose freely.
