at_limit issue

There's an option in conf files called at_limit, which is supposed to limit the vending time of @at vendors. And it works awesome... until server restarts for some reason (crash/planned reboot). After being reloaded from db, the vendor does not have that limit on them anymore.

I've checked around, and it seems that status is used for this:

ACMD(autotrade) {
...
	if( battle_config.at_timeout ) {
		int timeout = atoi(message);
		status->change_start(NULL,&sd->bl, SC_AUTOTRADE, 10000, 0, 0, 0, 0,
		                     ((timeout > 0) ? min(timeout,battle_config.at_timeout) : battle_config.at_timeout) * 60000, 0);
	}
...
}

And if there's no server restart, everything seems to work fine. But if it hits, that status is gone. I'll be looking further into the issue, but for now I'm clueless as to why it's gone and why that status is not reloaded, as it should be, especially since in sc_config it's mentioned as:

SC_AUTOTRADE, 77

So shouldn't disappear on relog/reload. Search in all files gave only 3 hits where that name is used directly: one shown above, one on end of status where it summons (map->quit), and one where it's named in enum.
