oooh another new problem, again with routing, in case anyone else has run into it:
```Update congestion history type 2
[INFO] iteration 35, enlarge 181, costheight 244, threshold 0 via cost 0 
[INFO] log_coef 0.507043, healingTrigger 15 cost_step 2 L 1 cost_type 1 updatetype 2
end grid wrong y2 x2 [1 114] , net start [75 175] routelen 139
 checking failed 19191```
(or_route.tcl then aborts)

:face_palm:
```[INFO] iteration 29, enlarge 181, costheight 202, threshold 0 via cost 0
