the first time the meteor just go caught in the blast, to replicate it I had to place the nuke a bit inside the meteor

mh why is our TESR called for an air block?

Well, theoretically some desync issue maybe? I suppose this could only happen on a server/client environment. In my initial attempts I can't reproduce this locally.
We can be more defensive in the sky chest TESR however.

I made it more robust, can you check again with the next release or the current nightly build, @Crazy-KSK ?

Sorry for the late reply.
I went and blew up two dozen meteors with zero crashes, so this has fix worked!
