Export to specified file with -o (without -n) does not work properly

[jakobharder]

C:\anno\testing>rdm4-bin.exe -g P4h_N4b_G4b_B4b_T2h -o small_gas_power_plant.rdm -i small_gas_power_plant.gltf
error: Invalid value for '--outdst <OUT>': No such file or directory small_gas_power_plant.rdm

small_gas_power_plant.rdm does not exist, but that's expected with -o and without -n.

Works if I place a fake file and then call with --force though.

The culprit is here:

rdm4/src/main.rs
