Does this also happen on Single Player maps or on LAN-hosted servers? Both using an .exe without the 64hz patch...

I tested it here. It would be good if other people tested it too:
Hosting a LAN-IP server (48Hz), not using the .exe patched for 64Hz, players will die immediately after falling — just like in your video. The host doesn't die, only the connected players do.

This seems like a default behavior predefined by Novalogic, which maybe just doesn't work on the standard 16Hz servers for some reason. But it could also be something Novalogic simply forgot, since hosts don't die. Just like they forgot the claymore behavior in Delta Force 1, where they don't work for hosts.

I wonder if we can edit the dfbhd.exe in that regard? In DF1, there was a patch that made claymores work for hosts. Maybe in BHD we can disable that fall damage before hitting the ground.
