This happens with recent minetest_game, works fine with older version

It may be related to recent minetest changes https://github.com/minetest/minetest/commit/3af5eef96463510a27cf06b9c3ecc9f1d04cdac6

Tested the mod, crashes with mod security on but works normally disabling it, using minetest-dev e403115 so not fixed on my side

This here should work just fine:

util.lua L106
-   io.close(file)
+
    config = {}
-   for line in io.lines(path) do
+   for line in file:lines() do
        if line:sub(1,1) ~= "#" then
            local i, v = line:match("^(%S*) = (%S*)")
            if i and v then
                config[i] = value_from_string(v)
            end
        end
    end
+   io.close(file)
end

Thanks, no more crashes. For now works fine with recent minetest_game and minetest server.
