I'm getting this error while trying to load the game.

It works without the other mods.

I managed to fix it by removing the "stack change" code.

Sorry I have been busy in RL.
Could you make a pull request on Github about the fix you did?

I have run into this as well. It seems to be related to the 248k Mod for me. It looks like that mod is changing something that interferes with how the stack size is being changed. I don't know enough about modding to be able to tell you what is being changed though. Possibly that mod is replacing logistic-robot with fu_robo_logistic_item? Changing the item from logistic-robot to fu_robo_logistic_item changes the error message to one about a table was expected.

I'll take a look at this.

Ok this issue should now be resolved. Please take a look. Any feedback is welcome.

This seems to have worked! Thanks much!
