Cadence Encrypted Simulation files missing in quartus_prime_pro-21.3.0.170?

Some more information:

I have tried adding to the simulation the files:

/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/ct1_hip_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/ct1_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/cta_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/ctp_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/ctr_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/ctra_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/ctrb_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.3.0.170-nodebug/quartus/eda/sim_lib/tennm_hssi_atoms_ncrypt.sv

This did not help!

I then tried adding files from the 21.2 release:

/hwnet/altera/quartus_pro/quartus_pro-21.2.0.72-nodebug/quartus/eda/sim_lib/cadence/ct1_hip_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.2.0.72-nodebug/quartus//da/sim_lib/cadence/ctp_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.2.0.72-nodebug/quartus/eda/sim_lib/cadence/ct1_hssi_atoms_ncrypt.sv
/hwnet/altera/quartus_pro/quartus_pro-21.2.0.72-nodebug/quartus/eda/sim_lib/cadence/cta_hssi_atoms_ncrypt.sv

This fixed the compilation.

Please note that these four files:
- have existed in every release since 17.1
- were missing in 20.3, and then delived as a patch. quartus-20.3.0.14. (Case 00575314)
- were included in 21.2
- are not included in 21.321

Is it possible that these files were inadvertently not included in the release?
