Game Crash each time I try to access a retainer

Time: August 7th 2015, 5:46pm PDT
Frequency: Every time
World name: Gilgamesh
Character name: Michiru Mori
NPC name: Summoning Bell
Class/Level: Arcanist, 23
Party or solo: Solo
Area and coordinates: Limsa Lominsa Lower Decks (8,11), Goblet (9,10)

Steps:
1. Hired my first retainer in Limsa Lominsa
2. Went to summoning bell to access the retainer inventory
3. Retainer appeared and menu opened
4. Clicked Inventory and game immediately crashed
5. Restarted the game, tried again, same result
6. Restarted the game again, teleported to Goblet
7. Same result at Goblet summoning bell
8. Logged in on another character on the same account: Iselia Shadowsun
9. Accessed both retainers with no problem
10. Logged back on Michiru Mori and again, retainer crashes me

It seems my character is somehow forcibly locked out of retainers by the game crashing for some reason, only on that one character, not on another character.

It also says "Venture Complete" on the first retainer - which is impossible because I have just hired it and did not give it a class yet.

11. Tried making a second retainer, same result - game crashes when I summon it.

There is no error code either, the game simply crashes and I get the Windows warning "Program is no longer responding" or whatever.

Is the character itself bugged because of a deletion from one account which had extra retainers and remaking with the same name on another account? That's all I can think of since my other characters are unaffected.

Please help ]:

Edit:

12. Logged in again but on DirectX 11 client and now the game doesn't crash. Very weird. DirectX 9 issue or it resolved itself somehow with a database update from squenix?
