The current 2v2v2v2 T1 Destroyer Proving Grounds event is allowing ships fit with modules up to Meta 5 to enter the event, which does not match the original intent. We have decided that the best way to respond to this bug is to adjust the event to allow meta 5 modules so that the official rules match the mechanics enforced by the game. This means that for the rest of the weekend the ingame text for this event will incorrectly describe a meta 4 module restriction.
Players are legally be able to enter this Proving Grounds event with modules up to meta 5 (Tech II).
Unfortunately we’re unable to update the information shown in-game without patching the client, and as this event only runs until Monday it will not be practical to make that change.
