[Observium] pfsense device id not working in v.3716

i recently did an upgrade from version 3476 to version 3716.

today i added a new pfsense device to my install, but the device id isn't recognized.

i confirmed the error on a different install of observium with the same version.

see attached screenshot.

is it a bug, or is it just me? :)
