I have built a simple sugar cane farm with a observer detecting if the third block of sugar cane is grown and triggering the piston beneath it.

Like this:

It works fine when i am Online. But if am offline the sugar cane just grows to full length without the observer detecting it.

Like this:

Should redstone work in forceloaded chunks? Or is this an expected behaviour?

Thanks for reporting.
What version of the mod are you using? I'm pretty sure this is caused by an issue fixed somewhat recently.

Hey, sorry for not mentioning that i am running on 0.16.6 and yeah it seems quite outdated.

The problem is that it is included in the newest version of the BetterMC Forge 1.19.2 modpack so i guess i have to open an issue on their github if you can confirm that this has been fixed in the newer versions.

I can confirm that this works in the latest version and 0.16.6 is the last version that had the issue.

Thank you for the quick reply your mods are really great!
