"Something is in the way" bug

[Locke_boy]

This message will CONSTANTLY appear while in dueling arenas. My guess? The little tiny sword NPCs on the ground. Lame? Yes. Bleh .. example: "Create Pool of Chaos" .. a very powerful spell, is totally obsolete because of this bug. I go to cast it, and "Something is in the way.". I try again, and again, and fail and fail. Sometimes I'll succeed, but only one or two icons of the spell appear. This bug makes MANY spells UTTERLY AND COMPLETELY USELESS. Don't magic-users have it hard enough already?

Also.. this message appears often, even out of arenas, even if something isn't in the way. I suggest that one be able to cast it even if something IS "in the way" (doesn't make any sense because other spells can cast over these "objects" that are "blocking the spell").
