The latest up to your lead mod made this mod crash on start up when the other mod tries to call this mod's data-util.lua . The pervious various of bzlead doesn't crash on start.

The other mod (I updated it with the major K2+SE update).

Thanks for report. I added some general library functionality, but it may have broken a mod using data-util. I might be able to fix with a small change on my side. I'll investigate more closely in the next day or so.

I'm uploading an unrelated update now.

Look like I'm having issues with the more entities setting which in my SE tweaks mod was to move it to the same subgroup as the iron chest.

Hm. Can't seem to reproduce the crash. Did you fix it in your mod (or do you have a save that can still reproduce it)?

I disabled it for how so the mod can load. It's still there but I commented it out for 0.0.12 of Tanks Tweaks for Space Exploration so the mod can load.

in data-final-fixes.lua

--if (mods ["bzlead"] and mods ["aai-containers"]) then

-- local leadutil = require("bzlead.data-util");
-- require("bzlead.data-util")

-- if leadutil.me.more_entities() then

-- change_subgroup("lead-chest", "container-1")

-- end

--end

Does something like this work.

    local leadutil = require("__bzlead__.data-util");
    local lead = require("__bzlead__.me");
    if lead.more_entities() then
      change_subgroup("lead-chest", "container-1")
    end
