(edited for correct patch version info)
Exported cars were messed up in the LCV4.1.8 (openbeta) patch [export was fully broken in the 4.1.9 patch] but they did export, now it fails with this warning every time.
I have double checked all my permissions and even tried adding exceptions to my Avast anti-virus free edition for Automaiton and the “[myusernameandpath]/Documents/BeamNG.drive/” folder (despite this not being a problem previously). I have confirmed that the BeamMP launcher is able to write to the “[pathto]/BeamNG.drive/mods” folder, so this appears to be limited to Automation. I have tried running Automation as Administrator, same results. Is this a known bug? Any suggestions?
