Have built up game over many months, but did a reinstall and the very bad behaviour in the same sandbox default run has none of the crazy behavior seen on first running 1.0.3 as an upgrade/ update Waits to be seen if the tram is frozen again on return to starting point, but this is already starting out with sparse pedestrians and no weird groups of misbehaving passengers ... yet.
Yup. Frozen signal on Sandbox run of default Line 1 back up from Hauptbahnhof to our starting point at Freimutplatz : there is a final signal before the final turn right ... maybe the Beta tester thought they were done at the prior signal when it changed as one might expect. Nope. Not quite there. Result: traffic signal ignored RED warning. Means nothing in Sandbox mode, but it does signal a Beta test fail.
a second run on Steam down Route 1 of Sandbox and a clear tram signal throws up RED traffic signal ignored. Why this time but not last time ? Last time it was a stop, as i recall. This was clear ... not the white ball warning, just clear thru. So the vexing bugs remain. Simple logic bugs. Oy.
