infolog says Circuit 0.9.9 crashed.
I'd suggest to use latest 0.9.10
Though i'll double-check if this error was fixed.
EDIT:
Couldn't find related commit/fix, there's a chance that bug is still present. Running 3v3 AIs (cloaky, htank, planes) on TitanDuel non-stop but it didn't appear so far. I hope it's not memory leak/corruption or old compiler's bug, those are hard to find.
Anyway, if 0.9.10 will crash - do not hesitate to post infolog.
EDIT2:
I'm suspecting there is something wrong with Spring.Reload. Size of LosMap returned by engine doesn't fit current map, hence reading out of bounds and access violation.
Maybe will be able to reproduce by playing with chobby and switching between small and big maps.
