When called on the server, the new block state is stored and propagated to clients and listeners as dictated
+ COMMENT by the supplied flags. Note that calling this on the client will update the world locally, but may not see the
+ COMMENT change persisted across loads. It's recommended to check whether this world is client before
+ COMMENT interacting with the world in this way.
+ COMMENT
+ COMMENT Accepted values of the flags are a bitset combination of the following:
+ COMMENT
+ COMMENT - 0b0000001 // 1 - PROPAGATE_CHANGE - Propagates a change event to surrounding blocks.
+ COMMENT - 0b0000010 // 2 - NOTIFY_LISTENERS - Notifies listeners and clients who need to react when the block changes
+ COMMENT - 0b0000100 // 4 - NO_REDRAW - Used in conjunction with NOTIFY_LISTENERS to suppress the render pass on clients.
+ COMMENT - 0b0001000 // 8 - REDRAW_ON_MAIN_THREAD - Forces a synchronous redraw on clients.
+ COMMENT - 0b0010000 // 16 - FORCE_STATE - Bypass virtual blockstate changes and forces the passed state to be stored as-is.
+ COMMENT - 0b0100000 // 32 - SKIP_DROPS - Prevents the previous block (container) from dropping items when destroyed.
+ COMMENT - 0b1000000 // 64 - MOVED - Signals that the current block is being moved to a different location, usually because of a piston.
