I'm using Zorro S 2.62.1 with a master script launching two backtests via zOpen() (Core 2 and 3).

Both child processes have LOGFILE enabled and a nonzero LogNumber. Reports and trade CSVs are generated correctly, but the native _pnl.csv and _pnl.dbl files are missing.

Running the exact same script directly (Core 1), even with zInit(), generates both PnL files correctly.

Is this expected behavior for zOpen() child processes, or is there a way to enable native PnL export?
