1: It skips that.
2: You need Haxchi to load the game now, since the game is no longer signed on your Wii U (No way to get around that).
3: It's random when a console crashes, and it's likely not the mods, but it would most likely help.
Ah, ok, BTW a lot of cool stuff was discovered while you were gone, like 3DS enemies now being editable, you can change the fonts in SMM, and I figured out how to edit the course editor layout and the UI in general in some cool ways with hex editing.
there's a chance we'll do one again but my wii u is banned, a few levels broke from the latest SMM update, and it's been a wreck so it might be a while. EDIT: it's been forever since you've been online, so wassup dude!
