Marching Goblins

[Thorsby]

Hello. I am pretty new to the site. I have posted a couple of puzzles, with the same rules, that no-one has solved.  

Marching Goblins Sudoku: https://logic-masters.de/Raetselportal/R...?id=00043L
Night of the Marching Goblins: https://logic-masters.de/Raetselportal/R...?id=000476

I was wondering if anyone would be interested in solving them, both or either. Night of the Marching Goblins is probably the easiest of the two, though I consider both to be hard.

Both puzzles has something that early on can make the puzzles seem broken. Two people has commented that they think the start of the first puzzle is broken. Both people realized they were wrong, but they did not solve the puzzle. I was hoping if somebody solved the puzzles, then people would realize they are not broken.

There was an error in Marching Goblins Sudoku, it was unsolvable. It has been deactivated. My apologies.

The Night of The Marching Goblins puzzle was also broken. Sorry.

Can you please check your other zero solver puzzles very carefully? Getting no solvers is very unusual, even for superhard puzzles. In fact, in all the 5000 portal puzzles there are only four at the moment: your two turtle puzzles, one Meta-puzzle posted today and an unsolvable puzzle because the author forgot the picture.

You could ask for testsolvers here.

I tried my two puzzles with zero solves. I found no mistakes. If anyone wants to try they are:
Turtle Sudoku 4s and 5s: https://logic-masters.de/Raetselportal/R...?id=00044K
Turtle Sandwich Sudoku: Always 9: https://logic-masters.de/Raetselportal/R...?id=00045P

I'll ask for testers for future puzzles.
