Well two bugs, one being the so called "Voldemort" bug (no idea why it's called that) have finally been fixed/are in the process of being fixed.
The first bug, which HAS been fixed is the nigh-instant shield recharge when out of combat. Shield recharge is calculated on a 6 second (or tick) basis. Previously, the shield regenerated at tick 0, 6, 12 and so on; this allowed users to quickly equip and unequip a shield module very fast, resetting the tick to 0 each time, so swapping a shield in less than 6 seconds resulted in an un-intended increase in shiueld regeneration. Cryptic has now made it so no regeneration occurs at tick 0, so doing this now results in no regeneration at all.
This "Voldemort" bug has been of great contention, making people think other players have 2 starship shields equipped at the same time, or swapping shield modules mid combat, to achieve the action of the previously mentioned bug. I shall refrain from explaining it until I'm sure it has been fixed.
