Duplicants wont build exosuits

I can't see anything wrong with those screenshots (except it still need deliveries of some copper), and I don't have any problem with my exo forge. Check dupes that have supply and storage job.

 

If it doesn't solve it, probably uploading your save game?

The only other thing I can imagine is the door is possibly obstructing the dupe who would usually be assigned. Or the missing copper is the cause and your upes are too busy doing other supply jobs, such as algae deoxydizers. The only other thing I can think of s you have something else accidently at priority 9....I do it all the time. but if you disabled other jobs then this shouldnt be the case

u need an exosuit dock, before they build exosuits

I just had this issue. There seems to be something going on with priorities, as I had mine in job auto-prioritize and advanced mode. Once I reset the modes and put priorities back to default, dupes immediately made a delivery to the exo-suit forge.

Can you manualy send dupe to Exosuit Forge by  Move To command?

Having the same problem. Dupes will deliver 15kg of copper and then no more. There are plenty of resources available/accessible and I've set the forge to max priority.

As Jam said, this is very frustrating because it kills the game; it's doubly frustrating because this was reported 2 years ago and still hasn't been addressed.
