Gui Click => Crash on Leaching plant 1

[LoupAndSnoop]

Problem Description

In seablock, I clicked on the icon to modify a leaching plant 1 to a different tier in the planner. Instead of openning the little menu, it crashed with this message:

The mod Factory Planner (1.1.78) caused a non-recoverable error. Please report this error to the mod author.

Error while running event factoryplanner::on_gui_click (ID 1) factoryplanner/ui/main/production_handler.lua:84: attempt to index local 'machine' (a nil value) stack traceback: factoryplanner/ui/main/production_handler.lua:84: in function 'handler' factoryplanner/ui/event_handler.lua:157: in function <factoryplanner/ui/event_handler.lua:114>

Reproduction

In seablock, I clicked on the icon to modify a leaching plant 1 to a different tier in the planner. Instead of openning the little menu, it crashed with this message. It happens every time I try to click on the leaching plant 1.
