Hotfix v0.30.4

Hi folks! Today's update is just a small bugfix patch to address a few issues reported over the past week.

Notable fixes:

• Fixed a multi-threading timing bug between texture garbage collection and MMO logo generation.

• Fixed a potential issue when a player was doing a quest, got distracted by combat, and then tried to return to doing their quest, if that quest had been destroyed while the combat was going on.

• Fixed pathfinding data for the Volcanic Market Stall model (which was resulting in players sometimes walking straight through the middle of the model)

...and a couple other minor bugfixes!

As always, huge thanks go to everyone who submitted bug reports or crash reports!
