This is the first node of the (first?) Veigar boss map, where you select a beginning power. After the first fight against a Minion, you'll reach a split path with a choice between an Item node and a Champion Item node, both of which are also invisible. You can fight those nodes by starting from the visible node on the left and tracing the paths down.
Well that's not supposed to look like that!
u/Zliplus, if you leave and come back (return to Runeterra for a second then re-enter the adventure), do the paths reappear?
On the other hand, when I restarted the app, it worked and the map is properly visible!
Very odd. Thank you for the update!
