Well, I thought that skipping turns could be avoided by not using full CPU to run rumble (leave a thread for GC, etc.), as it seems that I skip turns heavily (and randomly) against every bot (however I've examined only two bots which is selected randomly by rumble@home). I've been already doing weird optimizations everywhere, which destroys readability & extendibility.

Anyway, I've never verified that skipping turns could be avoided in any way. But anyway, being able to handle inconsistent scans always helps, that's why I decided a full rewrite.

Just found why I'm skipping turns so bad —

if (Math.random() < 0.01) {
  ArrayList<Object> list = new ArrayList<>();
  for (int i = 0; i < 10000000; ++i) {
    list.add(new Object());
  }
}

I forgot to comment this out.

Anyway, I think I'm still skipping turns badly when I run two clients together, as a newer version which is theoretically the same as previous version performs much worse.

I can never run more than one battle (1v1) at a time without skipping turns, because the computer I have at the moment is not well suited for this. Never even tried Melee. Maybe you should check if two Neuromancer battles would cause skipped turns and, if not, then specifically worry about ScalarBot.
