Yeah, Luthi crashed and Gadea couldn't avoid his bike. They changed the red-flag rules for this year, so if it happens again Luthi doesn't get points and the world championship.
Those KTM guys were so steamed I thought they were going to set him on fire and toss him on the used tire stacks.
In a nutshell, Talmacsi and Kalio were riding for KTM. Kalio had a legit shot at the championship, so team orders were for Talmacsi to NOT finish ahead of Kalio. At one of the later races in the season Talmacsi did a draft pass right at the finish line and beat Kalio by a nose, and a nose is by how much Kalio lost the championship. That sound about right, Papa?
