No MCTRUTH variables after rebuilding candidates in Sprucing + DV
Trying to follow what was done in this merge request here: lhcb-datapkg/AnalysisProductions!2320 (merged). Running sprucing on centrally processed MC removing the PID cuts applied at HLT2. My merge request is here: lhcb-datapkg/AnalysisProductions!2794 (merged). This appears to have run fine and has the expected PID removal but I have an issue where MC TRUTH information is not being saved in the final tuple, the branch is there just with 0 entries e.g. for Lb_TRUEPT etc. Within the first sprucing step I see this in the log:
RootIOAlg SUCCESS Reading Event record 1 within LFN:/lhcb/MC/2024/HLT2.DST/00263260/0000/00263260_00000045_1.hlt2.dst

So think that this issue could come from the sprucing stage. Whether I have specified something wrong in the options file or reading it wrong in DV after the sprucing I am unsure.
