I expected to have a normal route map

Instead, the route map ended up looking odd

Steps to reproduce the behaviour:

1. Make some stations and connect them with several lines
2. Make a route map sign that uses several of those lines
3. See the odd looking route map

• Minecraft Version: 1.18.2
• Installed Mods: Too many to list
  

看起来很正常啊，我的还只有一条线呢，你的都有交叉和折角，看上去很高大上啊
