Hey GalacticGod, how's it going bro?
So, the visuMZ library is gigantic, and I can't test the compatibility of all their plugins to guarantee compatibility.
What's common practice here in the community is that when a user encounters a problem, I do my best to try to solve it and force compatibility with my plugin. If you have a list of the plugins you use, I can check which ones might be experiencing instability and then I can give you a more precise answer.
In advance, WaterMap and WaterMapPlus use a visual layer system to inject sprites onto the screen, and a region ID system. If you have other plugins that use these functions as their core, we might encounter some problems.
If you need anything, just let me know.
Thank you for your question and for all the support!
