Not that I can tell. I did find something interesting though. I ended up losing that taskforce because they refused to shoot so I designed and built another different beam warship. In combat, this new beam warship worked. . . until I realized I didnt add emergency cryopods to it. I always forget to do this, so I added them to the class using SpaceMaster. The moment that I did this, in the next 5 sec tic, the weapons stopped working and I started getting the overflow error. It seems that editing your ship in SpaceMaster can cause this screwup.
I investigated further and clicked copy design on the orginal warship and built some more a year later. With this renamed identical but different class of warship, the issue continued even though it was a different set of ships and a different class for all intents and purposes. Then I designed a ship using the New Design button, the error was not carried over into the new class. I guess I found a bug? Maybe?
