Grid2 version ? In which situation are you getting this error  ?

Maybe you are using an old version of grid2,  Update to v3.0.12 or v3.0.13-beta

From other post it seems you are activating the target, focus, etc, units. This error happens if you enable the: target of target unit.  

Because this unit is protected now.

Ohh I see thanks! Well ToT I cannot see on default interface either anyways, I'll turn it off sadly.
