I have 
LazyVerticalGrid
with 
itemsIndexed
over a property which is 
mutableStateListOf
. Everything is working fine when I add items, but when I remove items via 
remove
or 
clear
on that list I get an exception trying to access non-existing items. It’s a call from inside the 
itemsIndexed
, looks like it didn’t notice collection has changed. Is it a known issue or am I doing something wrong?
Same with 
items
The code is pretty trivial
Copy code
LazyVerticalGrid(GridCells.Adaptive(72.dp)) {
            itemsIndexed(inventory.items) { index, it ->
                Text("${it.thing.name} [${it.amount}]")
            }
        }
and
Copy code
class Inventory() {
    val items = mutableStateListOf<InventoryItem>()
Exception
Untitled

Yeah I've seen this exception in Slack a couple times.

I see, thanks. @Andrey Kulikov is it yours? 🙂
Reproducable with desktop compose 0.3.0-rc1, not sure which compose is bundled

Yes, I’m using mutable state of immutable list now, it works fine. Thanks.
I see this issue is marked as fixed, but how do I know if it were already released in some public build? And if it also went to compose-desktop?

it was released in beta02 of the android build and in the first desktop release created after 3th of March(basically the latest one should contain it)

It'd be so nice that Google's issue tracker shows in a public metadata-field what releases will first include a given fix.
