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.

That was my main issue when going from rumble to melee. I basically destroyed all my code beautifulness because of those constant optimizations, but they really showed necessary, it became evident that my code was really slow when I released Medina, and it actually helped a bit on 1v1 too as some optimizations were not that bad and actually gave me more room to work on Knight.

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.
