Spidertron vanished by behemoth worm spawning on exact position

[echome]

I attacked the insects while they were creating a new base. They spawned a behemoth worm on the exact position of my spidertron. Spidertron vanished instantly without any destruction animation or something. The behemoth worm also got killed instantly. My char was inside the spidertron. After the loss of spidertron, my char was next to the dead worm, without any damage. Looks like a bug!
