Description

I create a function

function ShortRestOverhaul_RegainHP()
    print("ShortRestOverhaul_RegainHP called")
    for _, name in pairs(Ext.Stats.GetStats("SpellSet")) do
        if name == "CommonPlayerActions" then
            local spellSet = Ext.Stats.Get(name)
            if spellSet then
                local spells = spellSet.Spells
                if not string.find(spells, "Shout_SRO_RegianHP", 1, true) then
                    if spells == "" then
                        spellSet.Spells = "Shout_SRO_RegianHP"
                    else
                        spellSet.Spells = spells .. ";Shout_SRO_RegianHP"
                    print("Added Shout_SRO_RegianHP to CommonPlayerActions")
                    end
                end
            end
        end
    end
end

Then when I load my save, I see the following text in console. And the function can't work as intended.

ShortRestOverhaul_RegainHP called
bg3se::lua::stats::FetchStatEntries(): Unknown stats entry type: SpellSet

Api.md says

Ext.Stats.GetStats(type: string): string[]
Returns a table with the names of all stat entries. When the optional parameter type is specified, it'll only return stats with the specified type. The following types are supported: StatusData, SpellData, PassiveData, Armor, Weapon, Character, Object, SpellSet, EquipmentSet, TreasureTable, TreasureCategory, ItemGroup, NameGroup

So I report this as a bug.
