Not quite sure what specifically caused it but with replace stuff installed, pawns assigned to construction will just stand around. They sleep, eat, and recreate but will do no tasks, even non constructions tasks unless you tell them to prioritize doing the task. I haven't done any more testing but if anyone can let me know if this is replicatable or if it's just on my end that would be amazing.
