@Amcyeet I think so?, didn't touch it for 6 years, but my other version work so this might still do.
Best way to know is to try, and if it doesn't work, send me you log via pastebin and I'll see what I can do ;)

does this still work?

hey, can i get the spawnitem name?

Works now, thanks :D

@Star-X it should work as intended now

I don't understand why that is, because all I did was search IC, find what it does to vanilla chest, and do it to my Containers, and that should work, but it does not :/
I'll try to talk to v6

Still can't rename the containers from your mod, even with this version enabled. Thankfully now it doesn't crash.

I appreciate your efforts to fix it tbqh :)

Cool, will test in a bit.

Found the bug, I made a bad serialization error in the IC script implementation (my copy/paste was bad)

I've made an error somewhere, gimme a couple of minute to find where lol

I don't really care for pastebin (out of room on my account there thanks to the bullcrap 25 item limit), so here's a google drive link to the starbound.log that the game spits out with this mod enabled:

Do you have any crashlog? if so, post a pastebin link please, i'll make a Bug discussion

My container are completly new Object, but share the same ID between my 3 version, so you should only use One

Nope, seems to be completely broken. If this is enabled I can't load the game regardless of my save files or other mods.

I suppose the one and only other thing that might be causing it is that this mod is trying to load BEFORE improved containers, and thus the game crashes due to not having said improved functions "defined" properly (as that comes later in the loading order or something like that). Anyway, thank you for trying at least :)

Sadly I can't seem to use this bad boy in my current save, as trying to "upgrade" the containers to be Improved just causes the game to crash upon loading. I'll be doing a test to see if this happens with a fresh universe or not quickly; if it still occurs it's something wrong on your end.
