I have a weird bug I can not seem to remedy and was wondering if anybody else has encountered it and knows how to fix it with out reloading to a previous save.

I was in a dragon fight in riften, however the dragon flew of before being killed. However every time I am outside riften it shows a red dot on the compass indicating an enemy (that looks by the positioning of the red mark) to be stuck inside the gate or walls of riften (stable entrance) consequently I cannot fast travel nor can I make use of the carriages. Also no one seems to register a hostile presence.
The red dot also shows up when inside riften and close to the gate that leads to the stables, yet it does not have any impact on fast travelling or the surrounding npcs as they also do not register that an enemy is present same as outside.

Any help on this would be appreciated, I have already cleared my 360 cache after saving well away from riften itself yet the bug persists. I would rather live with it than reload as well tbh as i really can not remember how long ago this bug started. Nor how it started. Above just mentions what event preceded my bug as far as I am aware.
