-b option for Mac OSX binary incorrectly appending target file to batch-out path

[DMHoodoo]

Using:
macOS Mojave 10.14.6

My scripts are located in: ./are-resources/scripts/*
My intended batchoutdir: ./compiled-resources/

Running the following command:
./nwnsc -Q -n "/Users/hok/Library/Application Support/Steam/steamapps/common/Neverwinter Nights" -i "are-resources/scripts" -b ./compiled-resources/ ./are-resources/scripts/gs_m_load.nss

Brings about the error:
Compiling: gs_m_load.nss
Error: Unable to open output file ./compiled-resources//are-resources/scripts/gs_m_load.ncs.

I was able to create a workaround by removing the ./ in the target file and creating a new directory: "compiled-resources/are-resources/scripts" and running the following command
./nwnsc -Q -n "/Users/hok/Library/Application Support/Steam/steamapps/common/Neverwinter Nights" -i "are-resources/scripts" -b ./compiled-resources/ are-resources/scripts/gs_m_load.nss

This actually output the .ncs in ./compiled-resources/are-resources/scripts/ instead of ./compiled-resources/ like I originally wanted. It retrieves the scripts fine from./are-resources/scripts/ so it seems like the batch-out option has a minor issue.
