''Note:'' Version 5+ can have data that is based on the count of certain types of items in the item array. If you want to modify items in TM2020, you can come across issues when modifying the item array and it becomes rather difficult. This can be resolved by downgrading the version to 4. This downgrade should only affect item snapping - which is useful only when deleting items in the map editor.

''Note:'' Version 5+ was guessed by bruteforce, there's a chance something could be inaccurate.

''Note:'' The following information may be inaccurate, and was not verified for versions 5 and 6.

* '''snappedBlocks''': ''Values'' are ''indexes'' of the Blocks array (chunk 0x01F). -1 = snapped to an item and you should use the index of snappedItems.
