Connectors that were placed prior to the last update can be mined while in the belt dimension, leaving their nauvis equivalent behind. If one does so, and subsequently tries to mine the nauvis side, the game will crash with:
The mod Beltlayer (2.0.1) caused a non-recoverable error.
Please report this error to the mod author.
