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

Update: Did some testing today. If I make a new campaign, this issue does not occur, so it's likely related to save migration issues from 50.00 to 50.02

On attempting to export the Campaign Subset (all units, personnel, etc.) in an attempt to circumvent this issue after confirming it doens't exist in a new campaign, it failed. I presume this is likely related.
