Spring RTS Engine

Hi, spring crashed on me 3 times today, each time was when my immolator was firing at a incoming swarm of missile k bots, it's fine firing at long range but when they get in very close (touching distance) the immolator fires and then the game crashes.
The kbots were Arm on each occasion, my comm was also present each time dgunning the k bots close by the immolator.
I cant send messages after a crash for some reason so I'm leaving this post,

Cheers
