So, as explained in the topic, i need a solution which is able to solve:
Real-Room :A, Capacity of 8
Real-Room :B, Capacity of 10
Combined Real-Room: AB, Capacity 18

The combined room exists, there is a moveable curtain which allows to use the combined room, or the splitted ones.
I simply need a way that "AB" cannot be at the same time with "A" or "B".
I hope you see what I mean.
Do you have an idea how to solve this?

Liviu Lalescu: I added the feature. For each room, when you add it or modify it, there is a list of conflicting rooms.

Please don't forget, if you add a conflict R2 to R1, also add a conflict R1 for R2, otherwise FET will not start the generation.

Teachers' max building changes per day = 1 and min gaps between building changes = 1, real rooms.
Students' max building changes per day = 1 and min gaps between building changes = 1, real rooms.

The activities same time constraints with nonempty comments are ignored in the computation of building changes (a hack).
