Fixes https://bugs.mojang.com/browse/MC-136760 for Minecraft 1.12.2 (Forge)
If there are two entities in the same boat that is close to a chunk border, it can happen (~1 in 16) that one of the two entities is in a different chunk than the boat it is in. Minecraft deletes that entity when relogging or reloading the chunk.
This mod fixes this behavior, so you can happily store your villagers etc in boats.
Note: In Minecraft 1.12.2 entities are not automatically persistent when in boats. They can still despawn if they are not persistent.
Compatible with Astikor Transportation Carts!
