I used ID to automate Actually Additions' canola oil upgrade process, but I'm having trouble with it semi-randomly deactivating. Here's a picture of my setup:

In short, it reads the fluid block and if its name is "Refined Canola Oil" it sends a redstone signal to the precision dropper, who drops a canola seed. When the block's name is "Crystallized Oil", it sends a redstone signal to the fluid collector who picks it up.

Normally it runs fine, but occasionally when going AFK for a long period of time I come back to no power in my base. The setup is sitting there with the refined canola oil, untriggered to start. In order to start the process again, I have to break the variable store and re-place it, along with inserting all the variable card again--I haven't been able to find another method that works.

I have a similar issue when quitting and re-entering my world, although in this case the readers/writers show an error that the variable could not be found. The same solution (breaking and replacing the variable store) fixes this.

I'm running 0.8.4 on the All the Mods 3 modpack, with Optifine added.

Sound like a chunk-loading-order-related issue, I'll look into it.

In case it helps, the entire mechanism is located within the same chunk.

Hmm, then something else must be causing it...

I'm having something related. Whenever I enter the game I have to break replace my variable storages. Otherwise my setup just spits all my seeds out and ignores my redstone writers. An other way I can fix it is by taking out the variable card and reinserting it in each of the redstone writer in the system.
I have the problem in my automated smeltery too...
Now that I think about it I think all redstone readers/writers are having trouble. The smeltery have a lever to enable molten metal to flow from the smeltery to a tinker tank. I also have a lever to enable flow from the tinker tank to an casting table with an ingot cast. And when I start the game I have to remove->insert the variable cards (or break->place the variable storage) for the levers to work.

Might be related to #259

Also, might be related to an "empty tile entity" problem I had before, during world (un)loading.

I haven't been able to reproduce this issue, but the latest change should resolve it.

This change will be included in next release, if the bug still persists after that, please let me know.
