The problem seems to be this commented-out line. Restoring the break fixes the issue:

Cosmic/src/main/java/server/StatEffect.java

Lines 640 to 642 in 78e9944

	case WindArcher.WIND_WALK:
	statups.add(new Pair<>(BuffStat.WIND_WALK, x));
	//break; thanks Vcoc for noticing WW not showing for other players when changing maps

The author of that change probably tested it with !maxskill, which hides the problem
