free rider compound spawn error and other quest errors

The dragon eye quest event that spawns a free rider compound put it on top of an impassable wall.  It was not able to be entered, the walls can be destroyed with raise land/lower land but not the tile with the compound.  (walls from one of the titan event areas) 

I have also had issues with any save file that I have gotten either the legendary armors or weapons from a quest.  It seems to make the save file un-loadable.  (the arena and the elemental temple quests)
