So as a report: the Strikecraft tooltip doesn't crash, but isn't showing any text in its "point defense vulnerability" and "carrier bonuses" sub-headings. Also, the Valkazard's "SILVERSWORD Type A" still does crash, since it doesn't seem to have been updated for the new TooltipAPI yet.
...But that's it. Everything else works. New Meshan works as intended, things in Nekki work, the special ships work, all the mobile armors work, the Aleste crash from the change to how phase mines work is fixed (Aaaa-leeeeeex :argh:), it all works.
Thank you for taking the time to do this. I can now really get down with the new update!
