Vanishing Legacy Mark

Time: First noticed the issue on Sept. 12th, early afternoon PDT

Conditions: after zoning or logging out

Affected characters:
- Nekoyasha Azurewrath (Balmung)
- Akame Alzraqah (Balmung)

Unaffected Character:
- Mutoid Ma'am (Balmung)

Notable differences:
- Mutoid Ma'am underwent name & appearance change during beta phase 4 (Mutoid Man, Roegadyn M -> Mutoid Ma'am, Roegadyn F)
- Nekoyasha and Akame underwent minor cosmetic changes during Early Access/post-launch (race/gender were NOT changed, name was NOT changed, Benchmark data WAS imported)
- Fantasia was not used on any of these characters

Steps:
1. Noticed missing legacy mark on Nekoyasha after equipping summer event gear (equipment specifics are irrelevant, has no effect on bug)
2. toggled mark using /lmark command, mark was visible after second attempt
3. zoned, mark was not visible
4. toggled mark again, mark was visible after second attempt
5. zoned several more times, confirming steps 2-4
6. asked LS member to confirm problem (LS member was 1.0 character, apparently unaffected by bug)
7. LS member could not see my mark, I could see my mine, LS member's mark was visible to both parties
8. toggled with /lmark yet again, LS member could see my mark after second attempt
9. zoned away, and back to previous zone
10. my mark was not longer visible to either myself or LS member
11. toggled mark once more, both parties could see my mark after second attempt
12. Logged out, legacy mark was not visible on login screen for Nekoyasha and Akame, mark was visible for Mutoid Ma'am
13. Switched to PS3, confirmed step 12 for PS3 login screen

Ergo, the bug is cross-platform, very likely a character data issue. However, since the mods here are obnoxiously bureaucratic, here's some token information:
