"The wormhole does not have a gate"
Not technically a bug, but the way it's phrased could very well be viewed as a bug. If anyone didn't get an explanation from another player, they would report it as a bug anyways. I figure this is an appropriate forum because it's a problem in game. Jeff never purposely explained if "bugs" are only actual bugs or includes some poorly thought out issues.
Those words come up when someone not in a squad comes to an instance, which of course needs a squad to enter. Trying to go through the gate will automatically create a squad.
Solution A: Make the server automatically create a squad for the person upon first trying to warp through.
Solution B: Reword it to explain that the player needs a squad to enter and a squad will automatically be created for him if he tries again.
