Hello Kadeon!
In case you're still in the lookout, I use this plugin with a lot of Visustella plugins. While not everything is able to be synced (like the furniture system or such that modify map data, or the victory aftermath screen which does work but require you to turn off the "level up" screen), a whole ton of them work great. The Battle Core was very recently fixed to the degree that it works and syncs for all players too. A patch for that is on the Discord. In terms of my own experience with this and Alpha Net Z, this is on a whole other level in terms of stability and ease of use.
