I remember during the T:ANE beta that there were some automobiles that caused T:ANE to cry with pain they caused. The vehicles were so polygon heavy that the program refused to load them. On a more reasonable level, however, I ran into an interesting issue with a section of a route I have used for years, but always had trouble with a huge pause in one particular spot as if TS12, T:ANE, and even TRS19 needed to take a big breath before it continued. Figuring it was a high-poly count asset, I spend a few hours deleting and replacing content, checking, and removing, starting from scratch, etc. During this process, I never touched the track or the level crossing in that particular section.
Just the other day, I was driving and sure enough the ride paused dramatically then continued on. Like always going back again in that area was fine as if the problem went away. In this particular spot, I had a slight kink at some junctions I put in for a crossover and siding and this time, and like always I made that mental note to fix it. This time, I decided to finally fix it after 10 years of driving the same route. The process required doing some major track work including ripping up the level crossings. When I tested the track again, the problem went away. Given that everything was the same except for the now removed level crossings, because I forgot to put it back, I've come to the conclusion this asset is garbage. The crossing was non-operational anyway and was only scenic with some crossbucks and a road-crossing asset. With that being the case, a simple reworking of the road a bit higher with JR's wooden crossing asset worked fine in the same spot.
