At times the static chest (public chest that allows auto inserting) will seem to still allow auto input, but items dont actually make it into the chest/inventory. (Tested with PNC Omni Hopper and Create Funnel)
Breaking/Replacing (Or Mek Cardboard boxing/unboxing) the Chest fixes the issue.

Versions

Minecraft 1.18.2
Forge 40.1.52
Cloud Storage cloudstorage-1.1.0-1.18.2.jar

Steps to reproduce

1. Place Static Chest
2. Place Static Balloon on chest
3. Send chests into 'orbit' using static balloons matching the chest you setup
4. Wait...
5. Place Hopper/pipe/funnel against Static chest
6. Insert Items

Expected behaviour

Items to be insert, and not voided

Screenshots

My setup, but this could be setup in other ways for testing:

Additional info

I've had two occurrences of this happening,

One was before i had storages added to the 'cloud' (items wont actually insert until the storage is added to the 'cloud' which is working as intended) but once storage was added, items would seem to insert but the UI of the chests didnt reflect that items were being added.
[I tested this a few times, but only had this happen once]

The second instance of this happening was randomly after i slept through the night, went out to check on my production and found out it had stopped inserting (funnel kept inserting but UI of chest didnt reflect it)

Currently i havent found a way to force this bug to happen 100% of the time, it seems to be an occurrence at random.
