TrainCarts: Shift slapping inconsistent, console spammed with errors

BkCommonLib version: 1.13.2-v3

TrainCarts version: 1.13.2-v1

Spigot version: 1.13.2

---

Problem or bug: When I spawn any train and get it moving, the console gets flooded with error messages. And also shift slapping inconsistent. Works for some trains, breaks the train for some. The following error message gets printed around 20 times per second.
