Bug Description

In my standard Bernina activity with AI trains that I use in MP sessions I noticed that in X1913 AI trains unnecessarily stop before station entrance signals (because such signals are closed instead of being clear, therefore compromising meets and simulation advance. Things worked correctly in release 1888 both in single player and MP mode, but work correctly in X1913 only in single player mode.
Attached is a screenshot showing the list of AI trains. As an example train 1637_AI is waiting at the northern entrance of the Surovas station because of a red signal, even if the starting signals at the same station are already at green (see screenshot of the dispatcher window).

I have found the problem. In rolling back to the original version of MP signalling, a condition was supposedly not restored in an if instruction. I added it again and it works. Patch attached. I kindly ask an enabled developer to upload the patch.
