Fix #9882: When a belt receives items, they are first placed into the
toInsertlist and only actually inserted into the inventory on the next tick. However, during chunk unloading, thetoInsertlist is not persisted, causing all pending items to be lost.Similarly, in some cases when items leave a belt, they are added to the
toRemovelist. This list is also not saved during chunk unload, which can lead to item duplication.Testing confirms that the structure described in the issue can reproduce the item loss problem in both Create 0.5.1.j and 6.0.6.
