Bug description: Tried to add Contribution Points to a node in order to establish a link with another node, but when I tried to use Contribution Withdrawal, I get the message "You must first withdraw the production node."  Not sure what it meant by that, as I didn't have any other Contribution Points spent anywhere else (nodes or otherwise).  Thought maybe I could resolve it by contributing to a connected node and withdrawing that, but got the same message there.  Having tried a few others, I now appear to have 8x Contribution Points tied up between the following nodes: Western Gateway, Western Guard Camp, Toscani Farm, Forest of Seclusion.

So... is this a known bug, or... is there a step/procedure I'm missing somewhere to reclaim those Contribution Points?

Some people had this problem and it's because they didn't remove the contribution point from a production node, you have to take out the points in order. A production for example is a node that has potato, Ash timber,etc.

I found it's because I had a worker still on that node. I had to wait for all the stamina to drain and then I could. 

If I send a calpheon worker to mediah, I have found I couldn't remove nodes along his path while he was out.

Found him stopped him, was ok. Was a poor message to give me when it wasn't a node problem.

Hmmm... well, in this case, there aren't any workers assigned anywhere; haven't reached that point yet. Would have thought that if you simply invested in a node and then changed your mind, you could immediately withdraw the Contribution Points (similar to buying/disowning a home).

Something appears to have changed overnight (on its own?), and I was able to withdraw from some nodes (Western Gateway, Forest of Seclusion), but still have 6x Contribution Points tied up in: Western Guard Camp, Toscani Farm, Imp Cave, and Loggia Farm.

Edit: Okay,... in-game instructions, messages, and prompts need to be a LOT clearer on how these things work; players shouldn't have to beat the game with a stick hoping that candy will fall out. "Just for the heck of it", went back through and checked them all yet again, and... was able to withdraw everything, so I'm back up to full unspent Contribution Points.

can you try to run to the last node connected (you invested in) and talk to the node manager and try to withdraw? see if that works

There are some towns that you invest in. Like the one near Trent. Starts with a B but I dont remember the name. Once I figured that out it helped a lot.
