Hi, I'm getting this problem near my spawn area. Using Sponge 1.12.2 server with Forge. Unfortunately the latest build (190) did not help. I've noticed it appears when the second player joins the server near me.

Oh right, I released another version which should fix it. Sorry overlooked that method as well. Hope it works now, if not just reopen the issue.
