Got this a few times, playing mutliplayer with quite a few mods. Tends to happen when too much is happening on the map at once (i.e -> upgrading a lot of stuff at once) I'm going to guess its trying to update too much stuff? But I have no idea. :P

I was replacing Stone Furnaces with Steel Furnaces using Klonan's Construction Drones, and this crashed me to the main menu.

Hi there! Thanks for reporting this issue.

I've taken a look at the code and have identified what's causing this issue. It was a lack of foresight on my part that left some code exposed to situations where it didn't check for entity validity. I plan on uploading a fix today after work. Sorry for the delay, they've got me working a ton of hours since the pandemic.

As always, thanks for using the mod! I'll let you know when I've got the fix uploaded.

Ok, I just uploaded 0.18.11 with a potential fix for this issue. Of course, don't hesitate to let me know if you notice any more problems after updating. It's always possible there was something else that i missed. As always, thanks for using my mod and taking time to help me solve these issues.

No joy, I'm afraid. :( I updated to 0.18.11, loaded my save game, built a stone furnace and a steel furnace, placed the stone furnace, turned on Construction Drones and turned off my bots, then highlighted the stone furnace for upgrade using the upgrade tool.

I received this error: https://imgur.com/m9jPAxe and it crashed to main screen.

One more try!

I think this one is an easy fix. I don't have time tonight to playtest, but I just uploaded 0.18.12 which I think will fix this issue. Of course, let me know if you still have problems and I'll take a closer look. As always, thanks for taking the time to help me troubleshoot this issue.

Huzzah! I did the steps above with 0.18.13 and no crash! Success! \o/
