PC Sifa Is Broken On Br110 Db After Patch

Hello The Aussie Don here well once again a new Patch for TSW has broken something else in the game and this time its SIFA on the BR110 DB Loco on the new German Route when coming to each station sifa light comes on and i press the Q Button on keyboard and does not work i have tryed 3 keyboards i got and same thing happens sifa does not respond and spuds the train to a stop this issue needs fixing asap on PC Steam

 

You have to hold the sifa button for a few seconds before it registers. Same with the cab car.

 

I'm sure I read once that programming for a sustained key hold down is bad coding as it can play havoc with the input buffers. A quick press should be all that's required.
