📍 Description (REQUIRED)

Whilst using an auto-block placer setup with an observer clock, the block placer places concrete powder next to a water stream. However, the block stays as powder and does not harden until it has been clicked or updated.

📑 Steps to reproduce the Issue (REQUIRED)

1. Make a block placer with a water source or flowing block next to the placing area
2. Fill the block placer with concrete powder
3. Activate the block placer
4. The powder is not solidified

💡 Expected behavior (REQUIRED)

The powder should instantly harden upon being placed. This was what happened in previous updates.

🧭 Environment (REQUIRED)

• Server Software: Paper
• Minecraft Version: 1.16.5
• Slimefun Version: SF vDev-821

After further testing this is client side desync issue, not Slimefun.

Viewed with /cmi blockinfo to make sure.

Is it possible for one to fix the clientside issue somehow?

Is it possible for one to fix the clientside issue somehow?

Probably not, it's Minecraft issue. Try to ask Mojang tho.
The workaround for this issue is either you right click your blocks to update it or something else. or relogging to your server / changing world to update it.

Because it is an automatic concrete maker, I guess that I could simply make another observer clock next to the output position so it can update constantly.

If you wanted to make that automatic, you could use Block Placers and Android Miner tho. It's server side and should mine the concrete automatically. We should move our discussion to Discord rather than here.
