STOP THAT YOU!!!!!!!
NO COMMON SENSE ALLOWED IN THIS THREAD!!

Well, from the pic above it looks like the tank is not on paved surface. Don't planes have to land on paved surface in order to get a successful landing? If that is true and the tank is not moving since he is tracked how could he possible see a collision on his FE and get a successful landing before the collision message? If he was skidding towards the pavement upfront shouldn't the collision message appear first?
As for the common sense part, really, both the collision and the landing happened in the other guys FE in that order. What common sense explains the fact that the messages got to the other guy in reverse order? I know this is the one and only bug free software ever written but these attitudes don't help any one. If it is a bug HT will fix it and if its not well, nothing to do. No need to belittle every one questioning something.
So, if message A and message B originate at the same place in that order, how does B get to the destination prior to A? There are ways to do that if two different venues are used for the two messages but I am not sure RTs explanation included that. It could be as simple as two venues used for the two messages or it could actually be - oh my got, I am going to say it - a bug

"the server received the landed message from his FE and displayed it before the collision message was received by your FE and displayed."
Common sense? really? Server displayed but FE received
Let HT figure it out.
Can you post the film so we can see the sequence of events?
