The Baby Bullet *still* suffers from the HUD throttle interlock showing red when it's actually not interlocked. This bug has been "fixed" several times in the patch notes, however it obviously hasn't...
I seem to recall the UP loco on peninsula corridor also has the same issue. Another one of those bugs that dtg don't seem to be bothered about fixing
Their method of operation has resulted in such a long list of bugs that it's now very difficult to a) fix anything in a timely manner and b) really fix everything. Either some bugs seem to be forgotten or new bugs are introduced by the interference of new DLCs or by neglecting the need for thorough QA. .... a hair-raising story
