@JunGRail, I already answered your query regarding the 522 on the Polish forum - it's too long. The section between Warszewo and Kołłątaja is 6.59 km long. That leaves 23.65 km of the route eastwards. Unfortunately, no computer would be able to handle this (except NASA ), at least in this version of OMSI. Along with an extension of 522, you're potentially getting 56, 64 and C to drive and another 28 AI routes, these including the already missing ones. D'you feel like it?
