Description:
Network Extensions 2 (NeXt2) is a popular mod that expands the transportation network in Cities: Skylines by providing additional road and highway options. While this mod offers expanded features, it has been observed to significantly increase load times and should be unsubscribed immediately.

Reduction of Load Time:
NeXt2 has been found to have a negative impact on load times in Cities: Skylines. Due to its extensive road and highway additions, the mod increases the processing requirements during the loading process. This results in longer load times, which can be frustrating for players seeking smooth gameplay experiences.

Unsubscribing from NeXt2:
Considering the negative effects on load times, it is strongly advised to unsubscribe from NeXt2 to improve the performance of your game. Although the mod recently received an update for the latest game version, this update did not effectively address the load time issues caused by NeXt2.

To unsubscribe from NeXt2 and avoid any potential complications, please follow these steps carefully:

How to get rid of Network Extensions 2:
Why?:
NExt2 slows down the loading process. A mod break is likely to break your save game and a overall performance hit is present.
So here is how to get rid of it and still keep the networks thanks to a number of from scratch versions by Cylis. Credit for the guide goes to Archangel.

Extra Train Station Tracks (ETST):

Description: Extra Train Station Tracks (ETST) is a mod that introduces additional train tracks to your game, expanding the possibilities for railway infrastructure. However, it's important to note that using this mod can result in the inoperability of your save file.

When you start a new game with ETST, the mod modifies the game's underlying structure to accommodate the extra train tracks. While this enhances the realism and variety of your railway network, it can create compatibility issues with existing save files. The additional tracks can disrupt the existing pathfinding algorithms and cause conflicts with trains' navigation.

As a consequence, attempting to load a save file that was created without ETST after using this mod may lead to crashes, game freezes, or unpredictable behavior. It's crucial to understand that this incompatibility arises due to the fundamental changes made to the game's mechanics by ETST.

Therefore, it is strongly recommended to back up your save files before enabling ETST and starting a new game. This way, you can easily revert to a working save in case any issues arise or you decide to deactivate the mod.

While Extra Train Station Tracks provides exciting opportunities for railway enthusiasts, it's important to consider the potential impact on save file stability before incorporating it into your game.
