When you abort the Tutorial in a special Way This happens:

To reach this you click: [Skip] [Skip] [Exit Tutorial] [Yes]
(Speed after loading the game seems important to reproduce)

Actual Result:
user is returned to expected sector, but tutorial dialog has a good chance of not going away, leaving the user suck and un-able to interact with the world or any other elements in the UI

Expected result:
user is returned to the normal world, dialog closes and is able to interact with the UI/world in a normal way

@xarses
I was able to confirm it in a similar (but not exact manner)

from a game with disabled tutorial start (Tutorial: OFF)

1. Move away from world start station (440m)
2. Menu -> tutorials -> Tutorial startup -> [ok] -> [skip] -> [skip] -> [skip] ... until it places you

Result) You will be outside the station all together.

Expected result) You would be at the proper location inside the tutorial station.

(exit tutorial works, and places you back at your previous location)

Second test:
Tutorial: ON

[skip] -> [skip] -> [exit tutorial] -> [ok]
results in suck window, very high cpu usage as documented by OP.

reproduced 2/3 times tried. Speed does appear to help to reproduce. (IE while the world is still loading)
