Thank you, i didn't know about new update. Sorry!

After some hours into the game close to my base (i think) spawned some biter nests. And they started attacking, but every time an army of them (20+: lvl1,2 biters, spitters, prolly) attacks me, or my base, and if i see them, the game crashes. As is said, it crashes only if there's so much of them ...
