    Upon reinstalling TSW6 due to a mod conflict, I noticed that I have duplicate scenery tiles in the under mastery rewards tab. Is this a bug or should one of the duplicates be untoggled? If anyone has encountered this or knows of a way to remove the duplicate scenery tile "Office Building", please let me know. I do not have any mods installed, running the vanilla TSW6

    Stumbled across this thread whilst looking for something else. I've had the same issue, so you're not alone. It's related to route mods such as enhancement packs, timetables and lighting improvement patches. If you disable all your mods and relaunch the game then the duplicates disappear. If you have multiple mods for the same route, it's usually just one of the mods that causes the duplication.

    For example I have a bunch of mods for the WCML Preston to Carlisle 2019 timetable:

    - WCML PC 2019TT - The timetable itself
    - ModernShapBase - Base modification layer for the 2019-era route (removes textures and scenery items IIRC)
    - ModernShapOverlay - Overlay for the 2019-era route (adds extra / updated textures and scenery items IIRC)

    If I disable all of my mods and launch the game I don't see any duplicates.
    If I exit and then enable the WCML PC 2019TT or ModernShapOverlay mods (or both at once) I'm not getting any duplicates.
    If I exit, disable all mods again and enable only ModernShapBase I'm then seeing the mastery layer twice.

    I've just posted on the download page for the 2019 timetable to see if someone on the team can find the cause and fix it, in your case I suggest you pinpoint which mod is causing the duplication and then report it to the person who created the mod to see if they're able / willing to fix it.

    As you can see below I also have duplicate mastery layers for the Mildmay Line (Dalston Market) and LGV Méditerranée (Bastille Day).

    All mods disabled, no duplicates. Note Bastille Day, Dalston Market and Morecambe Illuminations each appear once.
