Ok, I upgraded to 2.2.8.. I had to reinstall the FinalIK package bridge as well.
I then reimported DeathMatch AI and now I have this error
Assets\Opsive\DeathmatchAIKit\Scripts\AI\Actions\Attack\SearchForAmmo.cs(29,28): error CS0246: The type or namespace name 'SharedItemDefinitionBase' could not be found (are you missing a using directive or an assembly reference?)
Same error occurs on IsAmmoLow and IsNearAmmo, thoughts?
