Fixed it, don't worry weoo, happens all the goddamn time. Basically when you add or move someone, first copy their name ctrl c and ctrl v into the right place, should be center automatically. And then get usercard img link and click the link button on first post under the name and put it in.

Usually right above the last [/SPOILER] for that group

If the centering happens the thing will rage, if the spoiler gets a text size, you're fucked and you'll have to redo every spoiler.
