I am have the same problem in 2-1 bullet games. Chrome gives error "SBOX_FATAL_MEMORY_EXCEEDED". It usually happens when I lose, which is to say, all the time :-)
Someone mentioned clearing the cache fixed it for them, but it did not fix it for me, only annoyed me that not I have to relogin to all my websites.
Can anyone explain why the web keeps crashing when I play bullet? Recently I just won a match, but it crashed at the moment I won, then I reload the page and they count that I lost.
