Erudition is allowing all points to be placed in the same skill
Erudition should bar the player from placing the points in the same skill
Thanks for the report, I believe this is a mixture of a system limitation preventing us from saying that a specific ability can only place points in a skill once along with a general desire to leave things like this so that a GM can decide to allow it.
That said I’ve filed a ticket so it can at least be investigated.
