I'm practicing all sigils run, and I got very frustrated by this bug. Even though I typed correct password of floor 6 (which, of course, I got from each of the star levels), the computer would reply "code incorrect", no matter how many times I type it. And the only way to fix this seems to get out of the nexus level and reload it (by getting into and then out of one of the puzzle levels, which are indeed far away from The Tower). I experienced this bug in two runs so far, which wasted a good deal of time. Has anyone experienced this? or anyone know what causes this bug?

Thanks frogtown, and I've tried it but it's hard... when I try to put a box under me on the tree, I just go directly through the box and get stuck between tree and wall and box! You seem to do it so quickly in that video without any setups...

Did this update broke the <weathertop> rock climbing also? Any alternative strats for that level? The best I've got is stacking two boxes in front of the star fence, but it's somewhat inconsistent...
