Have you tried //echo -ati2 * Uptime alias? $isalias(uptime) or //echo -ati2 * SET alias? $isalias(set) to see if you might have accidentally aliased them out (or done so incorrectly)?
If either of them return $true, then you can use //echo -ati2 * SET filename: $islias(set).fname to get the filename it's in and go check out what the problem is. If it's a single-line alias, //echo -ati2 * SET: $isalias(set).alias will return the offending alias code itself
