Minecraft bedrock edition is using 32-bit signed values to manage block rendering and player movement/coordinates as opposed to java edition's 64-bit signed values, resulting in extremely severe floating point precision errors that cause the player to fall through the world, be unable to move, cause the world itself to not render correctly, and limits the playable area of a minecraft world to just a few hundred thousand blocks (as opposed to these errors being completely unnoticeable all the way out to the world border in java edition). Refusing to address this bug will cause massive problems with parity across bedrock edition and java edition, and therefore this bug needs to be addressed as soon as possible if you are to continue making Minecraft java edition and Minecraft bedrock edition compatible.

An additional note: This is a serious issue and is not resolved, disregard the status please, as bedrock edition still uses the incorrect coordinate values. Do not ignore this issue.
