Sector Progress exceeding 100%

Not sure if this bug is actually worth fixing, but I felt I should report it in case it's a symptom of a larger problem. Basically, switching a Survival world to Ceative and back again, then completing contracts, will cause a sector's progress value to go over 100%.

I discovered this because I desperately needed an Area Welder early on. It was absolutely impossible to weld the projection for the ship I designed without one. But, the ship I was building was the one I was planning on using to reach space during a Classic Survival start, so I had no way of getting the parts for an Area Welder other than placing a couple fancy blocks in Creative and then grinding them up in Survival. (Devs, maybe consider giving us Area Welders at game start until the projection welding issue is resolved?)

Evidently, switching to Creative automatically sets each sector to 100% completion, permanently. Not great, since I now have a bunch of blocks unlocked early, but oh well. I figured I'd do the contracts anyway, for the other rewards and the sake of getting a good play test done. It turned out to be a bit awkward, though, because all the contracts have been unlocked at once and my sector progress value just keeps getting larger and larger.
