Crafted casting basin and spout.
Placed them.
If I look at them I see a red message saying, "error, plz report to create"

Did nothing with it after that.

well, screenshot? logs?

Well, it's been a long time since this error, and there have been several updates to the modpack, I will tell you and add screenshots if it appears again.

About the logs, I don't know how to gather them.
