[mostlynick3]

Re #380

Tested through

local function OnCommand(event, player, command)
    if command == "testtalenttree" then

        local t1, t2, t3 = player:GetTalentTreePoints()
        local dominant = player:GetMostPointsTalentTree()
        
        player:SendBroadcastMessage("Player talent info: "..player:GetName()..". Class: "..player:GetClass())
        player:SendBroadcastMessage("Tree 1: " .. t1 .. " | Tree 2: " .. t2 .. " | Tree 3: " .. t3)
        player:SendBroadcastMessage("Dominant tree index: " .. dominant)

        return false
    end
end

RegisterPlayerEvent(42, OnCommand)
