Full Changelog
Bug Fixes & Improvements
Performance Improvements
Fixed some npc issues, specifically in multiplayer
Fixed train carriages sometimes not positioned correctly on it's wheels after spawning in until it started moving
Fixed an issue where dispatcher offices would sometimes fail to unload, for example when going to the main menu while dispatching
Trains on the yellow line can now also start from Founder's Square Platform 1 & 2 if the dispatcher sends a yellow line train there by accident
Minor Bug Fixes & Improvements
Due to some critical bugs we have rolled the game back to version 1.3.3, we are working hard to get the update back into the game but there are some problems with AI Trains and Blocks not clearing that can make the game unplayable.
