I am new to WorldBorder and Dynmap.
I pre generated a 5k x 5k world with worldborder then did a /dynmap fullrender.

It is showing me these blank chunks in a pattern, like this:

I am running latest dynmap 3.0 beta 9 (Do I downgrade version?), on paper 1.14.4.

Open to any suggestions, please help! This map looks so unpolished :/
(Already tried going to those chunks to see if its a problem with the pre generation, the chunks are totally fine. The problem is on Dynmap's end. )

You can try to downgrade and let us know if that helps. If not you may want to try building in an un-rendered area and see if that makes it render.

Can confirm that this still occurs using any kind of chunk-pregeneration plugin with Dynmap, even on 1.16.1 using the latest build of PaperMC.
