[1.12.2] The amazing expanding waypoints file

[cerebrate]

Using VoxelMap in single player, every time I exit the Minecraft application and restart, all my existing waypoints are duplicated, often many times over. (See attached example file which turned less than a dozen waypoints into a 27,000 line monstrosity.)

There are no errors showing in the log, unfortunately.

This is happening for me on a realms.points file as well.. Very annoying to have to reset the file everytime i log off, I'm on 1.16.1 though.

Correction: the duplication doesn't happen on exit and restart. It turns out that every time a new waypoint is added, the duplication happens.

I have a potential fix for this issue, but I'd like to test it out locally before submitting a PR. Are there special instructions for getting this running locally? Or is it sufficient to following the general instructions for Fabric/IntelliJ?

it's happening on 1.16 fabric also, on servers too
