HSB shuts down sometimes

[N3k0]

This is what happened for the second time in 0.70. I left bot running and went afk when I came back after 2 hours I found out this: lost game in HS, game was on "lose" screen with rank portrait and stars, there was no bot running - he just disappeared. I checked out log and he got "error" 30 minutes before and probably just shut down without any notice or anything.

This is his last turn, end of log file:

[08:33:03.399 N] Error

It happened to me before but I did not checked log file then I thought that was one time thing and as it turns out it wasn't.
FYI bot was running as admin, everything is up to date(.net, etc), speed was normal, ranked game, normal profile.

Anyone had this issue? I'm really curious about that because bot didn't hanged, there was no error msg or anything - he just shut himself down.
