When flying in a group, the lights of other aircraft are not visible even when they are turned on. For example, landing lights, runway turnoff lights, navigation lights, taxi lights, logo lights and beacon lights are not shown. Additionally, other aircraft do not appear on the radar while flying, unlike when using VATSIM or injected traffic, where they are visible. These two aspects are very important to have when flying in a group.
PD: obviously all have same airplane and livery installed when trying it. Plane and livery look ok, prblem is just with lights.
