The error log is pretty long, so i put it in pastebin :
https://pastebin.com/cWpyxm8A

I think what happen was :

• I'm trying to import the request from blueprint using "Logistic Request Manager" mod :
  https://mods.factorio.com/mod/Logistic-Request-Manager

(Btw, CMIIW but AutoTrash can't import from normal blueprint, right ? Only import AutoTrash own custom blueprint ?)

1. Anyway,...when the item is being filled, i realize i set auto trash (manually) to many item to zero. So i delete the trash slot.
2. This error happen.

Btw, how do i get back AutoTrash being normal again, the GUI error is persistent, even if i disable the mod, load without mod, resave, activate AutoTrash again, then reload the save. 😭

Do i need to delete the "mod-settings.dat" ?
If it comes to that,...this is bad, i have plenty of mod with custom setting.

EDIT :
Turns out it was vanilla bug. A minutes ago there's new update (0.17.62) it's fixing this missing GUI error.
All my AutoTrash setting were gone though,..ah well..no problem, just need to recreate it.
