can't work now,if I change the side ,it will automatic change to the default lane，I have tried delete other mods, also can't work,I don't know if it only happens on me.

Hello o/
The are some details missing to investigate the issue... Here are a couple of questions that would be helpful:
0. Make sure you have the last version of the mod running
1. Have you tried both ways of switching? (Shift + L and GUI)
2. Have you also tried to remove and replace the inserter?
3. Does the issue happens in a new save too?
4. What mods did you use?

0 latest version is installed
1 Shift + L - works. GUI - no
2 tried. does not change

Thanks for the details! I'm currently trying to reproduce the issue locally. Seems the mods are not conflicting. Have you used older versions of Krastorio 2 Inserters previously in the save? And about 3rd point, "works" means there's no issue in the new game or it's the bug that works there?

yes, I used old versions.. I have this save from the release of space age. I had the same bug a few weeks ago, but the next patch fixed it.
when creating a new game, everything works fine.
if it helps, I can upload the save somewhere.

I tried updating the mod in all combinations but still cannot reproduce the issue... I suppose it happens due to bad initialization (that is done once per save). There were a probable issue in a piece of code that forced re-initialization.
Could you try version 1.1.5 and tell if there still the issue please?

Had this issue above, when trying to load my save with version 1.1.5 i get this error:

Error while applying migration: Krastorio 2 Inserters: Krastorio2Inserters_fix-to_1.1.5.lua

...erters__/migrations/Krastorio2Inserters_fix-to_1.1.5.lua:7: bad argument #1 of 2 to 'pairs' (table expected, got string)
stack traceback:
[C]: in function 'pairs'
...erters__/migrations/Krastorio2Inserters_fix-to_1.1.5.lua:7: in main chunk

I did try to start a new save file and that works so i assume this error only occurs if the save file had the mod before the update

The error seems to happen due to the issue above, the mod tries to load an incorrect (or rather "unexpected") GUI state. Should be fixed in 1.1.6 as there are more safety checks

in version 1.1.6 the bug disappeared. thanks
