i know it had to work that way, but i've triy also with player that are inactive from the very first days of the server, so they have not developed any science of tier higher than 1. They still see me and my ships...and automatically destroy them. But I repeat, when i try to activate cloaking nothing happens, no visible change in icons or in descripitions...and if i tap again the cloak button it always say "activating". (server Mareth)
