Despite many people praising the update for being the game's largest and most exciting, this update was also criticised for being the buggiest yet, with several bugs affecting gameplay. These included trains sometimes being unable to close their doors at some stations, trains being randomly despawned for exploits being detected despite not having exploits in use, AWS bugs, and most importantly, the approach signals at Leighton City, St Helens Bridge, the departure signals of Beechley terminating platforms and the depot signal of Beechley Sidings would sometimes turn into a Danger aspect irreversibly, with no way of being set back to Proceed by a Signaller. While most of these bugs have since been fixed, some still remain, negatively impacting gameplay.
The update was also criticised for several 'unecessary' station upgrades, primarily Stepford United Football Club and Leighton City, with some players angrily demanding that they be reverted back to their pre-V1.8 appearances.
Leighton West was criticised for being a pointless station as it has an extremely low train frequency after V1.8.0 despite its popularity in the early days of V1.8.0.
