Hello, I wanted to change the configuration of a ghosted Cybersyn Combinator, so I single left-clicked the ghost, and the following error text appeared:

The mod Cybersyn Combinator (2.2.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event cybersyn-combinator::on_gui_opened (ID 95)
Entity is not arithmetic-combinator or decider-combinator or constant-combinator.
stack traceback:
[C]: in function 'index'
__cybersyn-combinator/scripts/gui.lua:1893: in function 'create_window'
cybersyn-combinator/scripts/gui.lua:2137: in function 'open'

cybersyn-combinator/scripts/gui.lua:2308: in function <cybersyn-combinator/scripts/gui.lua:2308>

Version of the mod is: 2.2.1.
I'm playing a Factorio 2.0.14 non-SpaceAge game.
Error is reproducible (at the moment).

Hope this helps. Best regards, and thank for the useful mod!

Hm, not at home to test right now, but it looks like the combinator_description field might not be accessible on ghosts. Annoyingly.

Can you check if the description can be set on a normal constant combinator when it is a ghost? Maybe that's just something that's not possible, and then I'll have to check for it in mine as well.

Fixed in v2.2.2. There is an issue with the Factorio API where accessing the description field on ghosts is not currently possible.

The new version uses a workaround to allow configuring the description on ghosts, but it will not show in the tooltip until it's actually built.
