When me and my friends place Blocks from the Quark mod there are other block
example: When we place a spruce chest there is a water source
Is there any way to fix?

Do you have any more information such as other mods installed, version, footage of this happening?

Had the same issue on my server. Overnight the blocks all "updated" and were replaced or broken. Double chests turned into single chests with no sides, entire ore seams turned into random blocks from other mods, some chests turned into stairs or ores. I was using Quark as a dependent for Botania. Upon removing both mods the blocks went back to normal.

I was using Quark version r2.4-289.
I attached a few logs that hopefully have some info in them. I don't have enough JavaScript knowledge myself to parse it out.
