Yep. fleet viruses
I first came across it in the vanillia game...couldn't figure it out. then i found it in a modded version"7 Deadly Sins" good mod BTW
Obervations of the virus...seem the fleet thats effected loses 1.5 shield points per second, Also, the virus comes and goes. but does not dissappear. It also seems that the virus is also contagious. and will pass from fleet to fleet by proximity.
Conclusions?
First i thought it was the game helping to "kill Off' my amassed fleets. but that was wrong.
I have a saved game with -4000+ fleet cap. no virus
I have a saved game with -2000+ fleet cap and it has a virus in one of the fleets.
Any ideas?
And i serious about the viruses
