Graphics glitch - falling through bridge

I was walking through a door and onto a bridge at the Limsa Lominsa Upper Decks, at the Seventh Sage, when I fell through the bridge and onto the water below.
(11,8). I had to return to get out.

This has happened to me a number of times as well. It seems to be tied into abysmally slow area loading times.
I suspect it's due to high player congestion. I'm in Limsa as well with this happening, and with the Arcanist class being based there and only recently released, I imagine a large percentage of existing players are there as well.
That said, it's pretty horrid for a game no longer in beta.

Time: 8/24/13 ~ 7pm/11pm est. 8/25/13 ~1pm est
Frequency: 3 times to me thus far
World name: Hyperion
Character name: Demios Demonix
Class/Level: twice on arcanist ~20-24, once on lancer lvl 50
Party or solo: solo
In-game time: unknown
Area and coordinates: Limsa Lominsa Lower Decks, while walking towards vendors/market boards. Limsa Lominsa Upper Decks walking towards moogle mailbox (Circular Platform area). North Shroud walking over the bridge towards Hyrstmill.
Steps: While walking in the above listed area's i would suddenly fall through the floor, the lower decks time I was able to walk through the water over towards the fisherman guild and was able to jump back up on the docks on the map. The other two listed above areas my movement was restricted to the area on the map that would normally be able to be traveling on.
