I tested on MV version 1.6.3. Just to be safe, I made a brand new project with mv3d, srpg, and this plugin.
I'm not sure why the cursor would be misplaced for you, but this plugin doesn't do anything to manipulate the cursor or confirm key. Even before I made this, the cursor appeared in the right position, and the confirm key technically worked. Just the floor tiles were invisible.
If the issue persists without this plugin being on, then I believe that will help narrow down the root of it.
This example is not quite right. First, the parameter configuration used by all RPGmaker plugins is stored in plugin.js. Second, after you have configured everything, you don't need to remove other plugins from the rm plugin manager. You only need to remove the relevant files in the plugin folder. You are now making it more troublesome to use. On the other hand, in order to reduce the size of the package, you can only distribute the js and data folders. I directly overwrote the sample project of srpg gear mv, and then put the MV3D file into the plugins directory.
