I am working on a repair and fix to remove the block issues with-in this world.
There were also two dead mods those have also been removed as well.
Credit will be given to the author of this world.
To the author of this world nice work on it.
But the unusable buildings really killed it for me so I am fixing this and related issues.
Since there has been no changes in three years to this world nor has there been any reply back on this from the author in the comments and so forth.

I do see damage in the second screen shot tho. Is there any ways to disable the industructibility?

god those screenshots are beautiful

@Pinneapplelumps: The map was made for a public server, that's why buildings are indestructible. Since the Server Test Mod is continously changing, there's no permanent list yet. Right now it adds a respawn vehicle, a stripped down and heavily modified version of Small Ship Mega Modpack, takes out some components from the Assembler and contains loot prefabs and spawngroups. Once there's a final version, I will detail it further.

Could I get a list of what the '[Test Only] Server Test Mod' changes?

Also, can't delete/destroy/build onto any of the grids on the map.

@Entersprite Yup that worked, cheers!

@Pinneapplelumps: It's due to the extreme clean-up settings. Press Alt+F10, in the drop-down menu select "Trash Removal", below select "Voxels" and press "Suspend".

I don't seem to be able to destroy or place voxels. They keep resorting back to how they were, or in the case of placing, disappear. I've restarted the world and tried it in survival and creative, no luck.
