Yes its a big error but someone on gametoast.com
made a replacement file that will fix the problem. Click here
to download it. Go here
for details about the file. You have to copy this file to this location: BFBuilder\DataTEMPLATE\Editor\Data\Config\editor\b oundry,
as well as in every Data folder already existing along the same path (BFBuilder\Data[modmapname]\Editor\Data\Config\editor\boundary). If you have any problems with the file post them in this thread.
