Some people already mentioned here on the forums about a bug with stopping wipers. As far as I remembered, this was on the new TSW6 routes. Today I came accross this bug on Dresden - Riesa (yes the old route) with the BR143 in the snow. The right wiper stopped working, the left one was still going. Very anoyning bug, as you can't see a damm thing when it's snowing. Can this please being fixed soon? I don't know if this is a Xbox specific problem or not.
I would report such things as errors in any case. Since TSW already has a lot of errors, and every new route has more errors, it is usually an error.
Class 142 wipers on Just Trains' Blackpool Branches stopped working half-way through a service a few days ago. The Class 220 Voyager wipers stopped working on the Riviera Line this morning. Seems to be a core bug, as it's happening on many different DLC's now.
Yes, it looks like they messed up something in the core. On the BR143 you activate the left and right wiper separatly, the left wiper kept working and I could turn it off and on again, the right one did nothing.
TSW6 - Bringing a whole new meaning to "It's not a bug, it's a feature" by making the new feature into a bug.
