Trainz

My own route started in Trainz04 long ago. it has been upgraded to all the subsequent iterations. Now it works near perfection in 19 (117009). Upgrade to SP5 and it shows 2,469 faulty dependencies in red. Most due to the Texture missing thing. I am able to use PVsoft conversion tool successfully on each asset with this error. But i will not fix 2K+ assets. It is a bad joke. Whatever gains I would get with SP5 are not worth the trouble. Same for 22. It looks like the regular 19 is the end of the line for me unless anyone has a quick solution. Probably this problem has been noted before, but I failed to see it...
