The modules seem to have a weird bug. It has happened to me very often that I can not see the cooldown time with the modules ingame. The module fields in the game are then simply gray after using modules.
It happens with the Fulgora, Aion & Vigo.
Another Problem that appears for serveral times: I fired Storm Missiles at an enemy right in front of me. According to the module, the rockets were fired because the cooldown starts. However, the Missiles are not visible and do not hit the opponent.
Used ship was the Vigo.
