Hmmm. It turns out the totally warped and deformed platform was _not_ the cause of the strange skewing.
After I got it all back together with the new platform, and got it re-calibrated, I tried the 50mm tower again. It had the same skewing...
I've decided to start adjusting the top of the z-tower again. I've adjusted it to ~18mm, as apposed to the other tower's ~20mm.
Those adjustments produced these results:
Better, but the affect seems to be getting less. My new theory is that the issue isn't actually the height of the top, but rather that the linear rods on the z-tower are being flexed. Letting off the top reduced the flex. So, I've twisted them a bit and am trying the print again.
