So I was trying to figure out the exact teleport dimensions for the rings so pasted a bunch of walls on one and sent it to another. The sending ring blew up from the damage and then this error occured:
The mod Transport rings (0.2.5) caused a non-recoverable error.
Please report this error to the mod author.
