why is farl removing twice as much trees / rocks on opposite driving lane side than is needed?

Blueprint strings please

Are you using FARL 4.0.3 ? Older versions had a bug that caused possibly huge areas where FARL removed trees.
Your blueprints work fine for me with FARL 4.0.3:

If you are using the latest FARL version and still have the issues, please upload a save

looks to operate as before now tnx, good work :)
