I was working on a scenario last night for the Cajon Pass Modernized workshop route and discovered that the various track markers (platform, siding, and destination markers) have suddenly become invisible (except for the "posts" on each end that you can grab), and that while they can still be grabbed with the mouse cursor, that the end posts will just snap back to their default position as soon as you let go of the mouse. I initially though that it might have just been an issue with the scenario (I had started work on it back before the game was rebranded as "Train Sim Classic"), but only a few minutes ago, I tried again on a brand-new route I created just for the purpose. The same problem happened there. While they still seem to be fully functional, being unable to adjust the length of platforms and sidings won't be very conducive to future route-building endeavors.
I cannot reproduce this. I can move route-based markers in the World Editor and scenario based markers in the scenario editor. Just gave it a quick try on Cajon Pass (Modernized). Everything is working. The update changed nothing in the game code. Make sure everything in the filter (PC Screen symbol) is ticked. (Except for Audio Markers, they're too big and distracting unless you wanna edit them.) Also make sure that the route/scenario is not locked.
I got this issue now as well on a scenario I'm building. Can you tell me what object set filter you had to tick in order to fix?
It's been a while since I've had that issue. This is what worked for me just now during a test, hopefully this'll help
Thanks for replying so quickly. I'll try it once I get back on TSC and report back. Edit: It worled. I was looking at the wrong panel initially but your screenshot showed me what I actually had to click to see the options. Thanks.
