Receive error on robot mining of non connecting induction rail. Unable to hand mine the rail and bots crash.

7655.660 Error MainLoop.cpp:738: Exception at tick 1730613: Error while running event on_robot_pre_mined (ID 15)
wireless-charging-lib/src/main.lua:490: attempt to index field '?' (a nil value)

I am unable to reproduce this error. Is it only a single rail that cannot be removed or multiple?

It was a series of them. they weren't selectable by me (only by deconstruction planner) and weren't flashing like others right next to them.

Were they behaving normally when you placed them or broken immediately?

The error will no longer be raised in 0.2.4 but it's a condition that should be impossible to occur. If you can provide any info on what you did to the rail entity that caused this one to go bad that'd be great.

They were broken immediately. I laid a horizontal line of 10 of them at a station and 8 of them were not selectable and were not connecting (no flashing icons). 5th and 6th in the line worked but the rest messed up. Haven't been able to reproduce it since.

Do you have any other train-related mods? Maybe there is a conflict somewhere. Otherwise I have no idea what could cause this.
