TFS 1.X+ ERROR [Warning - Action::loadFunction] Function & Lua Script Error: [Event Interface]

[Svira]

For a long time I can't deal with some engine errors. All internet searched! Engine TFS 1.3 for tibia 8.6.

Error1

[Warning - Action::loadFunction] Function "increaseItemId" does not exist.
[Warning - Action::loadFunction] Function "decreaseItemId" does not exist.
[Warning - Action::loadFunction] Function "increaseItemId" does not exist.

Error2 - monsters dont drop loot. in scripts.xml onDropLoot(it doesn't matter if it's active or not, nothing goes wrong)

Lua Script Error: [Event Interface]
data/events/scripts/monster.lua:Monster@onDropLoot
data/lib/core/container.lua:11: attempt to call global 'getLootRandom' (a nil va         lue)
stack traceback:
        [C]: in function 'getLootRandom'
        data/lib/core/container.lua:11: in function 'createLootItem'
        data/events/scripts/monster.lua:11: in function <data/events/scripts/mon         ster.lua:1>

Any idea how to fix it?

yes, dont merge datapacks if you have no idea whats going on. Basically you are trying to use methods that arent existing in your source.

in errors there are original tfs 1.3 files, from the beginning komoda goda do not work etc. Is there a chance to fix it?


EDIT##
Solved.
added in global lua

string.split = function(str, sep)
    local res = {}
    for v in str:gmatch("([^" .. sep .. "]+)") do
        res[#res + 1] = v
    end
    return res
end

function getLootRandom()
    math.randomseed(os.mtime())
    return math.random(0, MAX_LOOTCHANCE) / configManager.getNumber(configKeys.RATE_LOOT)
end
