I'm having a problem with the object set filter button in the creator side of TS2015. I want to make a free roam scenerio for Sherman Hill using the Big Boy but it doesnt show up in the available locomotives tab. I found from looking on here, that reason to be I have to go into the object set filter and choose "all developers". The only problems I click on that little button and it doesn't do squat. Before anybody asks the obvious, yes I have a fully licensed and registered version of TS2015.
