Our little fleet has recently completed an upgrade of the fleet base to Tier 1 on the engineering tier. We also have a full science tier (10K science xp). Now here's the kicker; I'm not seeing ANY more science projects I can contribute to. What gives?
once you max out a tier, in your case the science one you have to do a special upgrade project before receiving more science projects. in the case of the science tier it is the construct/upgrade communications array project
