Some 1.13 snapshots conflict with other 1.13 snapshots and other versions in general. This is due to world generation changes along with version 1.13 being an unstable versions of Minecraft due to heavy code changes. It is important to know all discontinued features in 1.13 along with how to load its conflicting snapshots and the dangers in doing so.

Dangers

Loading 1.13 snapshots regularly and for different snapshots will most likely lead to regular crashes and potential world corruption. To attempt to avoid this, you must not only make frequent world backups, but you must stay out of chunks that have important contents. Instead, try to stay in older unimportant chunks. This will prevent them from resetting when the world loads. It is also important to back up your spawn region, if you believe it also contains things that are vital to the world. Finally, try to stay out of areas containing other general 1.13 generated content.

How to load 1.13 snapshots

The easiest way to load conflicting 1.13 snapshots is to use world save insertion. The basic idea behind it is to make your world save unplayable by deleting important files before forcing the game to generate a new level.dat for it. This will retain your world but reset your player. Basic instructions are detailed below.

1. Make at least one world backup.
2. Delete or move the following files and folders in their entirety (moving is suggested if you want to keep any discontinued data contained in these files): "level.dat", "level.dat_old", and "playerdata".
3. Load up Minecraft and click "Create New World".
4. Inside "World Name," type out the exact same name that the world you're trying to load has. This is how we trick the game into generating a new level.dat for the world. For example, if your world is named "New World", fill in the name as "New World.”
5. Set the settings how you want them; it’s suggested you keep the same seed as your previous world. Additional information on seeds and settings changes are on seed manipulation and world save insertion.
6. Click "Create New World"

Upon world load you should see your world but have a fresh new player and be playing in a previously impossible version.
