Very simple report here. I am on the latest version of Forge and the Latest version of the Mod and when starting up Minecraft, in the Logs I find this error. I tested every single mod in my modpack and it only showed up with your mod. Hopefully, it can fix an issue later down the line :)

This isn't an issue, so don't worry about it. And it'll likely disappear in the 1.16.2 version.
