Hello, I have problem with my dynmap, I used chunkpregenerator to generate chunks, but my dynmap is rendered with some weird holes:

Did you leave dynmap running while the chunk pregenerator was running?

I had dynmap on, but dynmap generation was off

Duplicate of #2485

these are either errors in the world generation or errors in fullrender. To me, it seems like errors in the world generation (the pregenerator didn't fully generate edge chunks) and as such dynmap can't fully see them.

I suggest teleporting to each black spot on the map and then doing a /dynmap radiusrender 100

Going to mark this as a duplicate now since that seems like the most likely candidate. There's no quick solution other than a player visiting all unrendered chunks

didnt helped

Have you cleared web cache? Teleporting to those spots and radiusrendering will solve this.
