Good day
I have atached the savefile where you can reproduce the problem
The problem is currently fixed (although it has made me paranoid of other stations eating resources without producing anything)
I have tried the following stuff to fix the problem.
1.save and reload -> doesnt work
2. pause and unpause the station -> doesnt work
3. fire everyone, continue the game, rehire everyone -> worked second try
This savefile shouldload you in directly into a lumber yard which is affected, and there is another lumber yard in the left which is also affected, they have probably cut between 50-100 logs without producing anything.
(lumber yard of the left is located a bit further than the tend camp)
I currently had 4 carriers, even thou i dont understand what the carries have to do with the lumber workers being able to produce wood or not.
