Since the latest I think hotfix, it might have been the update and we didn't notice at the time, but mine and others who have static units have seen a number of bugs emerge.
The two ill focus on here on my Vox Relay Unit and Teleport homer.
Vox Relay:
Since the update it has been rendered unable to fire. It initially aims at the target before slowly turning away and never even trying to shoot. Instead just saying "Ready"
Teleport Homer:
This one is a forward deploying unit that just gives other units the big forward deploy. It can't do anything but unload. If you tell it to unload in the deployment phase it will unload first thing just like normal. However, if it is told to unload post game start, it will not.
