I have an error, which comes from your mod.

thx, I'll look into it. In a few week I should also be able to find some time for to continue this mod

Dude, the "remains" apply in corpes in the base of factorio is (worm) destroyer, remains for archive"small, medium, and big" (age space), but in the case "sandworm", by size "small, medium, and big", in the case enemies.lua (base) linked for your file sandworm.lua in add remains, I tried it, for find of the problem, I hope for send this tip, is some hardccore by programing in the version 2.0.59 and late, for this error by this mod, greentings

Looks like this effecting multiple mods that add demolisher-like entities. See the behemoth enemies mod discussion here: https://mods.factorio.com/mod/behemoth-enemies/discussion/68700dab4b06eb281b5dcdbb

There is a temporary workaround that appears to work for both mods by creating a duplicate of the big demolisher remains and renaming them to what the game is expecting. This is a workable solution until the mods or game are patched.

Temporary fix instructions:
- Open the game's properties on steam and click "browse local files".
- Then inside of the file explorer window, navigate to data\space-age\graphics\icons
- Copy the file named big-demolisher-remains.png and rename the copy to big-sandworm-remains.png
- Repeat the above steps for medium-demolisher-remains.png -> medium-sandworm-remains.png and small-demolisher-remains.png -> small-sandworm-remains.png.

This will probably produce the wrong color remains for this mod, but it's just a temp fix. You could probably grab the correct remains texture from the mod's files and use that instead if it bugs you.
