Sensors deleted since r14315

Hello,

Recently updated our test environment from r14315 to latest rolling.
Immediately on next polling of devices, some sensors where deleted.
Test environment doesn't have the most diverse OSes but this was observed on the following devices;
HPE ProCurve devices - dbm sensors from HP-ICF-TRANSCEIVER-MIB was deleted
Synology devices - disk health status was deleted
Dell iDRAC devices - fan and voltage sensors was deleted

I haven't had change to look more into it than that currently
Will update with some debug / dumps asap
I noted some updated code specific for snmp in latest versions which I guess could be a reason for this.
