There's a Damaged Stadi Group Cruiser which bugs out and is untargetable among the South West spawns.
Recent changes to the timer for Virus Upload changed it to be disproportional to the amount of damage/clearing speed of a 5 man team across all Tiers, if it really needs to be longer by design than some middle ground pre-change and now should to be considered.
The newly introduced "white eyesores" in the background cause immense FPS loss and blindness, they should be changed.
I've found that if a ship has Phoenixed itself into an asteroid or satellite, and can't be targeted, you can hit it with Warp Plasma, and it'll still eat the ship.
