Excuse me but my english is very bad and I work with a translator.
I have the following problem and I think this is also the problem of Csuhi81.
I built a crude wash tube and a bot takes the clay pot (dirty). Another bot brings the clean clay pot to the storage. And for this to work, another bot uses a bucket to collect water from the waterstorage and bring it to the crude wash tube. This also works for a while and then nothing works. Why? The bot with the bucket is standing in front of the waterstorage, wants to fill it, but it is already full. That's why I taught the bucket and it went on for a while. I have watched this time then. At some point this bot empties his bucket into the CrudeWashTube and the bucket is still full. And if he now executes his order to fill this bucket at the waterstorage, it stops because the bucket is already full. This does not work then, although the Crude Wash tube is empty. I have to empty the bucket first and then it goes on for a while until it is back in front of the waterstorage with a full bucket of water, even though the Crude Wash tube is empty.
He can not execute his command to fill the bucket, as it is (still) full.
Thanks
Norbert
