I’ve placed T4 thralls in all of my workbenches. I’ve even destroyed and rebuilt all of my benches and replaced my T4 thralls. I’ve captured NEW T4 thralls and used them to replaced my existing T4 thralls with the new ones. Thrall Taker never updates.
I’ve upgraded my entire base from sandstone to T3 materials and Mason never updates. I’ve tried building a new structure from scratch using T3 materials and Mason never updates.
At the moment, I have about 50% of the journey steps that will not complete no matter how often I do (and re-do over and over) the final steps. What’s the point of having these if they will never complete?
