Figured it out! The updated lirc package overwrote my hardware.conf file, so I had to add the various arguments back:

#Chosen Remote Control
REMOTE="Custom"
REMOTE_MODULES=""
REMOTE_DRIVER="udp"
REMOTE_DEVICE="5000"
REMOTE_SOCKET=""
REMOTE_LIRCD_CONF="logitech/lircd.conf.logitech"
REMOTE_LIRCD_ARGS=""
