3 weeks ago This is caused by certain array being accessed from more than one thread. We fixed this before with other arrays by using thread safe arrays but this one slipped under our noses. I found the problematic array that needs to be replaced with thread safe version https://github.com/Gennario/RotatingHeads2/blob/main/src%2Fmain%2Fjava%2Fcz%2Fgennario%2Fnewrotatingheads%2Fsystem%2FHeadRunnable.java#L15
We should also take a look at other arrays to make sure this issue doesn't linger.
