Cursed Tree Jacket

I swear, my Tree Jacket is cursed! (Link to pattern. The Original.)
Either that, or there's some kind of force in the universe that doesn't want me to finish it while the weather is still cold enough to wear it this season. Which amounts to the same thing: a curse.

I have now knit 5 sleeves-worth for that sweater. The first one, I accept as pattern-modification testing. I decided to knit the sleeves in the yarn-over pattern instead of the garter stitch, and the first sleeve was a test-sleeve.
Fine.
So the second and third sleeves got me a completed sweater! BUT the sleeves were WAY too huge. They dangled, and really annoyed me. So I ripped them out and re-knit them, decreasing 12 sts in the 24 rows right at the underarm. (See mod description on Ravelry here.) Now that was better.
And then there were 4 sleeves worth.
(Note: that fourth sleeve took me a few months to work, as I couldn't decide how I wanted to proceed with yet more pattern modification.)
Now that I had the re-modification all worked out, I figured the fifth - and last - sleeve should go by in a jiffy. Well, it did! And I got it finished tonight!
Alas, when I went to take apart my Denise needles, I realized that the needle tips I had been using were the (smaller) ones I had used to pick up the sleeve stitches at the underarm, and not the ones I was meant to use to actually knit the sleeve!!! GRRRRRRRR!!!!
And RRRRRRRRRRRRRRRRRIIIIIIIIIIIPPPPPPPPP!!
Again.

Now my Tree Jacket is waiting patiently for me on my footstool, waiting for me to start knitting the sixth (and f*cking LAST) sleeve.

*sigh*

Note to self: double and triple check the needle tips on the cord BEFORE stating to knit, when using an interchangeable set.
