Also using bobs logistics & adjustable inserters which prefer over long hands.

These mods load fine with Lignumis. It must be something else. Some mod is changing the long handed inserter graphics that causes this.

That would be https://mods.factorio.com/mod/reskins-bobs?from=search

I can't reproduce it. It loads fine. Can you try to find a minimal setup that gets you the error?

both Yea & No i just not interested to trim down 202 mods Tho thanks for the help. Can provide a save game on git tho. Also I don't want you ether to have to bother with this needle in the haystack

"i just not interested to trim down 202 mods"
Dito 😉

yea

The same error occurs
but if I disable these two mods, the error disappears:
1. https://mods.factorio.com/mod/boblogistics
2. https://mods.factorio.com/mod/bobassembly

I also contacted the mod developer with this error https://mods.factorio.com/mod/reskins-bobs and he gave an answer https://mods.factorio.com/mod/reskins-bobs/discussion/695bce2043a2ecd16916e403

Hm. It's not easy to decide how to handle this. I really don't want to be incompatible with the reskins mod but I also don't want to duplicate vanilla code and miss any future updates from Wube for that code. In my opinion such mods should apply their changes for vanilla entities in the updates phase. But that probably won't happen in this case. It's neither a small change for the reskins mod to change it nor for me to copy the vanilla code. My time is currently very limited so for the time being I'd say the mods are just not compatible. I'm sorry I don't have a better answer.

Thank you for the explanation

I should have known better, but I updated my mods, and have got a very similar error, except its attemtping to "call field 'setFilename' (a nil value) rather than index file 'sheet'.

Im tinkering at the moment to see if i can figure out which mod caused this. I thought it might be "long handed stack inserters" required by Moshine, but that wasnt it. Nor was it Rubia which also adds a similar thing.

Ok, looking at the inserter in a game loaded without lignumis, the inserter has tags for:

Cerys, PlanetsLib, AAI Industry, Enhanced Shadows, Cargo Ships, Inserter Fuel Leech, Combat Mechanics Overhaul, Castra, and Paracelsin.

I can confirm it is not caused by ANY of those. Will continue testing.

Thought it might be Tenebris Prime as it adds "bioluminescent" versions of many items, but nope. Guess i gotta do this the hard way and disable mods one at a time till i find it.

I forgot to release cf-lib. I did that just now. Please update it.

Ok, sorry for the comment spam, but im now officially lost. Im sure ive missed one mod in my cluster of nonsense. Time for dramatic action. I never look at Lignumis now as its been running comfy for hundreds of hours, so im going to open up the code and stop it from even trying to give the burner long handed inserter graphics. If it never tries to access Filename, it can never run into an error...

Oh-wait a dang second. Now its giving me an error in the integrations file regarding burner mining drills and inserters, now thats interesting...

Ok, success, i got in after basically telling Lignumis not to look at Filename for long handed inserters, burner inserters, burner mining drills, AND stone furnaces. I just commented out the lines in vanilla and integrations that referenced them. I'm completely lost on what mod is actually causing this bug, but this will do for now.

I need to remember not to update my mods midway through a huge run, its a recipe for disaster...

I forgot to release cf-lib. I did that just now. Please update it.

Ah, thats some amusing timing - i started that last comment then jsut got on with it before posting as i realised there wasnt a point in giving you a running commentary. Never refreshed the page to see your reply until i then finished the comment and posted it.

Just installed your update and its loaded right away, thanks!
