public transport router doesn't respect oneway tags, uses wrong bus route

[prototype99]

app version: 3.3.7+ live
device model: google pixel 2
Android version: 9 (patch level 5.4.2019)
map version: osmand live united kingdom england 18.4.2019
router: osmand
routing profile: public transport
from: sayer court (PE2 5FN)
to: headmasters peterborough
issue:
the correct bus is bus 1: orton > werrington/millfield, router uses bus 1: werrington > orton. perhaps as a result of trying to make the bus route go the opposite direction it doesn't respect the peterborough bus station's oneway roads

There are 3 relations of that bus, I couldn't catch which relation is missing stop or have extra stop

It might be the error is in the data itself.

well, you have the citi 1 bus (https://www.openstreetmap.org/relation/2578822), which runs the routes 1 orton (https://www.openstreetmap.org/relation/8524218), 1 werrington (https://www.openstreetmap.org/relation/8524216) and 1 millfield (https://www.openstreetmap.org/relation/9396783).

1 orton is the southbound part, and 1 werrington and 1 millfield are the northbound part (1 millfield is effectively 1 werrington except it ends at the bus depot). at the end of 1 werrington the bus becomes 1 orton, and at the end of 1 orton it becomes 1 werrington, or if it needs to go into the bus depot it becomes 1 millfield.

alternatively, i have this official route map which may or may not help with understanding the problem.

as for the fact it's hard to troubleshoot when there's three different relations to check, i do plan to soon explore ways of simplifying the troubleshooting as there are in fact three more route variations that i have not yet mapped that all reuse the same route segments which feels like a nightmare to maintain unless it's made simpler.
