In the skill guide widget, you can't view more than two sub menus

[SchauweM]

When opening a skill guide, you're able to view the first menu of items. Clicking on a second menu item such as "Bows" on the "Fletching" skill guide will result in the replacement of title for that child id to "Please wait" (English.pleaseWait in the client). The widget will open said sub menu but the widget will be stuck from there on until you close it.

I've already done some debugging and it appears that the client gets stuck on Main.java:236 in the client. Other functions won't get called from skill-guide-plugin.ts.
