AI trams are skipping the stop signal

Hello.

I encountered a big problem when applying trams to my upcoming Golczewo 2.0 map. Konstal 4N trams are working correctly, but when I'm trying to add Tatra KT4Dt trams to the map, they're slowing down and ignoring all the traffic lights on the map. Does somebody encountered that problem too and have a solution for it? It is stopping a release of the map. Of course, I'm using the "KI" versions in ailist file.

Logfile is clear, I'll try to reinstall them one more time.

/edit: It didn't work, tram is still skipping the signal.

It worked after changing this parameter to 1.3. Thank you.
