Lag causes hellburn engine to break.

This probably relates to how the "new" system reduces lag by temporarily putting stuff off until the next tick, if I remember correctly about being how that works. Couple that with the new extremely high tick-rate, and I could see stuff being needing to be shoved off to the next tick more often due having less time available to occur.

Let's hope it doesn't relate to the lag fixes, because fixing something like that would require really fundamental changes.
