The External Playtest Server is now open for testing. We did encounter an Interlock bug in testing today, but have decided to let players on to start testing and fix the bug as soon as possible.
In short, Accuracy isn't being added into Interlock rolls, resulting in a high number of misses during Interlock combat. At lower levels, this won't be as noticable as at higher levels. We will fix this bug as soon as possible and update the EP server. Free Attack rolls are not affected by this bug.
