Rasa 2.0 Forms does not validate extracted slots and asks the next slot

No, I am talking about a different issue, the slots of trigger messages is the bug that makes my bot unusable. I started migration to rasa 2.x on September 28, having a deadline for a demo on October 5. Then I realised that it was not my fault my forms were not working, I updated from rc3 to rc4, found a workround for rc4 on October 7, and on October 8 you released version 2.0. Which changed again how forms should work (from rc4), I updated again my bot, but my forms still do not work, and I cannot find a work around. 7 days later, I still have no solution, no demo, and no plan for a fix from rasa.

What should I do? Go back to 2.0.rc4? Go back to 1.x?

(And if you remember this thread Rasa 2.0, how are forms working?, the problem exists for almost 30 days, and I was hopping 2.0 would fix it - which didn’t -, and the bug has been closed). I really do not know how to proceed.
