Additional context

Add any other context about the problem here.

I am aware of the issue, but am unable to fix it. Fixing it could corrupt current worlds.

I will however investigate the repercussions further

For the moment I'm disabling Tinkers IO to remove the block and then load the pack again.

What's the trigger?
I had a lever attached to the basin before adding the transfer node,
Just don't put the transfer node on the basin?

Noted, thank you for the very very fast response

Yep, it's the transfer node.

Huh, apparently it does not cause corruption to update, so fixed in next update.
