We never truncated item and location names tbh

This will result in weird exceptions when the name overlaps, right? I wonder if the Exception could be a bit more verbose here

Something like this (extremely loose and unoptimized code)

if len(name) > 16:
    name = name[:16]
    if name in ...:
        raise Exception("After being truncated, the name already exists. Item link names must differ in the first 16 characters")
    ...

Then again I'm often quite a lot more prone to writing a million user friendly exceptions than other devs, so maybe this is not necessary

We never truncated item and location names tbh

An alias and player name can be shown when getting .player from something. They were limited to avoid breaking various games/clients, but itemlinks breaks them anyway

Could do that, I just borrowed the already used barebones style

if len(name) > 16:
    name = name[:16]
    if name in ...:
        raise Exception("After being truncated, the name already exists. Item link names must differ in the first 16 characters")
    ...

So this isn't technically true because of names like " I Had Spaces At The Start". But I doubt the specificity of the exact requirements is worth putting into the error message, so "the first 16 characters" sounds great
