My dupes wont tinker with the generators, I think since the latest update.
The Control station is set to prio 9 and has metal both in it and readily available. The generators do not have a prio setting.
Dupes are doing prio 5 tasks ahead of tinkering as the generators are apparently set to prio 5 but I cannot find a way to change this on generators without manual input like coal and manual generators.
Steps to Reproduce
Build a power plant room with power station and natgas or petroleum generators and have any other operating task set to 5 or above.
This issue has not been confirmed by a developer yet.
