I've got the following game crash:
The mod Lane Balancer caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Lane-Balancer::on_tick (ID 0)
LuaSurface API call when LuaSurface was invalid.
stack traceback:
Lane-Balancer/control.lua:128: in function 'GetBalancerInBelt'
Lane-Balancer/control.lua:221: in function 'OnTick'
Lane-Balancer/control.lua:10: in function <Lane-Balancer/control.lua:10>
stack traceback:

I know that Lane Balancer is causing the crash, but it may be affected by the way in which Warptorio removes/replaces the surface, so I've posted in both places.
