[V453000][2.0.16] Electric weapon damage 3 and 4 have the same research cost

[ManaUser]

Both cost x1000 of the same 7 science packs. For context, 4 is the first level of infinite research.

I guess this isn't necessarily a bug, perhaps there's some technical or balance reason for it I'm missing, but it breaks the pattern of all other research, so it looks like an oversight to me.

Given that this is not causing any crashes or making game non playable and it is about technology costs, i am going to move this to balancing.

Thank you for noticing and reporting, this is just an oversight so I've fixed it for the next release.

Thank you!
