I tested with the weekly release 16-01-2026 and all three replays pass. I then added #1748 (which was later superseded by #2460) and all three replays mismatch. So this is just a side effect of the uninitialized cellBounds.hi variables in Pathfinder::classifyFence.

Superhackers has decided this is an acceptable outcome. These 3 replays were part of a set of more than 9,000 replays, hence the chance is less then 0,1% that a game mismatches.

These replays will not be part of the replay pack.
