Hey xy,

I'm having a weird problem with my spaceship, when I open the FCC to configure the radars I cannot close the window again.
Doesn't matter how often I click on the X the window won't close, i have to releoad a save to close it again.
sadly this completely blocks me from using DART, as factorio seems to save the open windows.
so if I try to configure everything save and load again, this FCC Window is still open and I cannot close it.

(Additional info: this WAS working fine until I placed (and later removed) a FCC in the Blueprint Lab)

Oh, what strange behavior!

I also suspect it might be related to BPL. Oddly enough, the close button also opens another dialog box showing a different number of turrets, which, to make matters worse, are also invalid 😒.

I've tried to downgrade to 1.2.9 (in case this bug is a new one introduced by the changes in 1.2.10) - but same behavior, so downgrading is not an option.

I think I've found a solution that makes the internal logic for chaining the GUIs (which is part of the problem) more resilient - at least now I am able to close the offending GUI.

Will need some time to make my final tests, but that will be tomorrow morning - now it's too late for me 😴

V 1.2.11 with a fix for your problem is online

Yes it works again :)
Thanks for your quick fix.
