Fighter sensor hits changing between save, load, and MegaMek sessions

[SuperStucco]

In the attached 49.5 campaign, there is a Lucifer LCF-20 aerospace fighter with one sensor hit. When I save the game and reload it, it turns into 3 sensor hits. When I deploy the fighter and it takes no additional damage, it also comes back as 3 sensor hits. If I GM the damage down to 1 sensor hit, and save/reload or deploy again, it once again converts to 3 hits.

I've noticed similar behavior with FCS (fire control system) critical hits.

There's a couple of custom infantry/BA loaded, from here:

When the campaign is first loaded the fighter will likely have 3 sensor hits. GM modify the damage to 1, then save and reload; or deploy it in a quick scenario.
