Update: DemoServer improvements and fixes - All ticks are now accepted - exposed an editor only API to inject ticks (avoid serialization roundtrip) - cleaned away tick logging - it generated too many logs Ticks are now caught, which is nice, but it looks like it's not validating them all outside of demo playback (saw only 2 players doing it on a perf capture). That'll be next. Tests: added temp debug assertions that would catch any discarded tick - played the new demo, and there were no more assertions.
