Message From Space (Compass Copies #8)

Tremendous thanks to starwarigami for testing and improving!
- Standard Sudoku, Kropki Pair, Arrow, and Odd/Even Rules Apply — not all constraints are shown in the starting grid.
- Compass Cells
- Each compass cell points to another cell in the given direction that contains identical constraints (or lack of constraints), with the distance to that copy given by the cell's digit.
For cells marked ?? the direction is to be determined by the solver.
In the finished puzzle each compass cell is identical to its copy (with the possible exception of its contained digit).
NOTE: The location of some arrow parts, circles, and tips, must be deduced (extending from copied arrow-parts that lack tips and bulbs); these are not copied from existing cells. - Solve Online

Notice how each cell that has a compass direction or ?? is identical in its constraints (dots, even/odd marks, arrow-paths/tips/circles, thermometer paths/tips/bulbs, etc.) to its target cell, which is determined by that direction and by the distance given by the digit in that cell.

Added an explanatory sentence about extending arrows (thank you, @SKORP17!)

The circle and arrowhead need NOT be in the same directions/distance in the copy as they are in the original.
Diese Aussage widerspricht doch aber dem Beispiel und der Beschreibung (identische Bedingungen!!).
Ist das jetzt also so zu verstehen, dass lediglich ein Kreis bzw eine Spitze kopiert werden, aber die Ausrichtung eine andere sein kann.
Was ist mit den Linien, können die auch anders ausgerichtet sein? Muss eine geknickte Linie auch im Ziel geknickt sein?
Ich fürchte, die Lösung wird durch diese Unklarheiten sehr erschwert.

Just for clarity, if a compass cell appears in the middle of an arrow, is the directionality of the arrow and/or distance from the circle/tip retained in the target cell, or does the similarity simply end at the border of the cell? i.e. the target cell just appears in the middle of another arrow with stems leaving in the same directions, but no restrictions on where the circle/tip are. Furthermore, I'm assuming that target arrow segments in adjacent cells (with matched stem directions) will link up into a longer arrow, and shouldn't be treated as independent arrows.
Finally, if a target cell is also a compass cell, can it refer back to its original compass cell as a target? I think I'm fairly close to finishing the puzzle, though I may have broken it horribly as this seems to make the difference as to whether or not I can continue.

manushand: Hello @jgreenfield! The copy of a cell to another cell brings only the aspects of that single cell itself; the arrow entering (or leaving) the cell could go in completely different directions outside the copied-to cell that what it does in the cell-copied-from. The circle and arrowhead need NOT be in the same directions/distance in the copy as they are in the original. I hope that makes sense!
Secondly, a target cell may indeed refer back to its Compass Cell as its own target. You have good eyes. :-)
