In CWR² we used a modified AI behaviour script as the Corepatch team is using. Unfortunately, this seems to cause more problems than its solving. Nothing uncommon in this [d]wonderful[/d] game engine.
With this hotfix, the original AI scripts are used in CWR² again.
Before you replace the pbo files in the mod folder with the ones included, please make a backup of them! Just in case you want to keep them or because you had no problems so far.
