Ideally identical looking to the ones you get when a Sim dies. Or a way to keep my game from being stuck in infinite loading when returning to Edit Town after placing remains with buydebug...

If you're using decrapped Store content, you might want to take a look at this: https://www.tumblr.com/phantomfixes

Hm, I do have a few store items but nothing in use at the moment. Would I be ok to just replace them all with non-decrapped package files? Always been a bit unsure about how exactly it works and what the difference between de-crapped/non files is.

Honestly, I haven't spent much time looking into it, but I assume that decrapping premium content (and the fixes for it) addresses errors like sims resetting while using it, or accessories (spoons, knives etc.) not showing up. I remember fiddling with premium content a long time ago, but it's been so long that I couldn't even tell you if mine is decrapped or not. I can, however, confirm that I was getting the same infinite loading error after using buydebug.

Your best bet is to just try out the fix and see if it helps.

ETA: but for convenience, I recategorized the urnstones (both the normal basegame ones and the future ones) to be accessible in regular buy mode instead of buydebug. You can find them under Decor \ Sculptures, Decor \ Misc and Lawn Decor.

The buydebug crash is caused by the DecrapFixes package, distributed by various people but I think originally by KissingToast. The items don't have to be present in the save for it to happen, the second the debug catalog thinks about the broken object is where the game soft-crashes.

It is premium items specifically that require this package if they've been decrapped- so using unmodified or cleanly decrypted versions is recommended, these don't require any fixes.
We aren't technically allowed to discuss redistributed Store content here, so I can't speak to the validity of the versions linked. The best advice I can give is to start with the original .sims3packs and run them through Pescado's S3RC (and not decrapify) yourself- where you get those packs from is ultimately your business.

I did some misinformation correcting on the topic of what decrapify does here and here.

I plan to release thorough edits with all other fixes applied of most Store objects in the future, to the same degree as something like Buckley's Disentangled hairs so that they are distinct enough to upload here.
