I know what you mean about the command forcing a players sitting at the Force Respawn position of "1" to spawn .. but this command absolutely worked while we had SM 1.3 installed where nothing else seemed to work, including ZR's own respawn setting in zombiereloaded.cfg.
Everytime a player is Force spawned by using the !zadmin Force zspawn menu, the next 'dead' player in line essentially becomes that "1" anyway, so it can & does work to force the respawn of any player who dies - whether that be 1 or 20 players who die.
Given the choice between angry players complaining that there is no way to respawn into maps with no spawnkiller or AFK Cleaners - i.e. Barricade maps & a few select Escape maps - or putting that simple bypass in at the time to correct the situation, I know what I'd prefer!
