Sorry if this should be reported as a bug instead, but I'm assuming this is something I goofed up, and I don't have an actual bug report. I haven't played in forever and tried to load up the last autosave, but got the following error:

"An interface already exists under with name: silo_script

stack traceback:

\_\_core\_\_/lualib/silo-script.lua:261: in function 'add\_remote\_interface'

\_\_base\_\_/control.lua:68: in main chunk

stack traceback:

\[C\]: in function 'add\_interface'

\_\_core\_\_/lualib/silo-script.lua:261: in function 'add\_remote\_interface'

\_\_base\_\_/control.lua:68: in main chunk"

I assumed this was an issue with a scenario, since that's the last thing I remember playing, so I tried just starting a vanilla game, and got this error:

"The scenario level caused a non-recoverable error.

Please report this error to the scenario author.

All game files verified on Steam, and I don't think I have any mods enabled (although I don't have any experience with the new mod manager). The campaign missions were able to open correctly. If anyone knows how to fix this, please let me know.

I didn't see a Scenarios folder in roaming, but I found the one in Steam and deleted it. I verified the files, so it redownloaded the files, but I'm still having the issue. I also uninstalled the game through steam and reinstalled and still have the problem.

Can you send me your save game? I think you will need to clear the control.lua from inside of it
