CaloClusterEff throws bad Calo CellID exception in some events

Running the master version of last friday (19th Nov 2021) of Moore, the CaloClusterEfficiency algorithm throws an exception on the find operation from line 165 in some events. With the following summarized output:

...
CaloClusterEff                        FATAL  Standard std::exception is caught 
CaloClusterEff                        ERROR bad Calo::CellID
HLTControlFlowMgr                     FATAL Event failed in Node CaloClusterEfficiency/CaloClusterEff
HLTControlFlowMgr                     FATAL *** Event 976 on slot 0 failed! ***
...
ApplicationMgr                        ERROR Application Manager Terminated with error code 3

I believe this comes from the return of the largestWeight function. In case the table entry is empty it returns an empty Result type. The exception is caused by a cell {'Spd', 'Outer', 0, 0} since 'Spd' and 'Outer' tags are the 0 indices.

To reproduce the error I'm running the following option file:
