So I heard there are problems with 1.14 rendering, but yet I have a modded 1.16.4 Forge server, it has around 8 mods but the render distance is about 4 chunks, even though I set it to 18. On an unmodded server, the render distance is fine.
The weird thing is, for example when I stand on a block, it renders 4 chunks around that block, but when I go farther from that block, to the left, let's say I go 5 chunks. When I return to that block, the blocks which I rendered by going 5 chunks, remain rendered! So what I'm trying to say is, the render distance around ME is small, while the blocks I already explored REMAIN RENDERED even from a long distance.
Sorry if I didn't explain that well, but is there a way I can render more?
