A recent issue I've noticed is that all the thumbnail images for routes are not showing up in the build menu or the in game store. Could anyone have a look into this issue when they are able to.
Doesn't happen to me. These are locally stored images, I wonder what's causing this on your side. As for the ingame store, that's probably due to the current maintenance they're doing.
Build menu's fine just like torfs, as for the store menu.. I think they want me to buy a specific route but I cant be certain.. That is the only thumbnail showing up on either the route, loco or home pages. ¯\_(ツ)_/¯ So yeah I think definitely store maintenance related.
