If you are tired of being unable to click on gondar/treant here is the solution.

It involves replacing gondar’s and treant’s models with others that look exactly the same but contain a few additional polygons to make clicking easier.

1. Make sure local files are allowed by the registry:

Just doubleclick the localfiles.reg file included in the Units.zip.
 Or

>> Show alternate method <<

2. Download the Gondar & Treant Models archive and extract it in your WC3 directory.
