[Issue] Interstellar map in 2470 broken

Brief Description *

It seems that the data update borked the map for 2470.
Redownloading and extracting did not fix things.
Note, for example, the capellan comonality coexisting with the capellan confederation over a century after the former was supposed to dissolve.
I know data is scant for that era, but it seems to me that going with the old data for that error would be better.

3. Steps to Reproduce

start campaign in 2470 (or nearby years)
go to interstellar map

Final Verification

• I confirm this is a single, unique issue that hasn't been reported before
• I have filled and provided all necessary information above
• I have included any and all logs, custom units, and CPNX (save) files
• I have asked on MegaMek Discord about this issue
• I have confirmed this issue is being opened on the correct repository: MegaMek, MegaMekLab, or MekHQ

Start by reproducing the issue in a campaign set around 2470 and opening the interstellar map, using the attached save file and unified_log.log. Compare the current and old map attachments and verify that the historical faction data no longer shows the Capellan Commonality coexisting with the Capellan Confederation; done means the map displays the corrected era data without breaking the campaign.
