Error while running event automatic-underground-pipe-connectors::on_object_destroyed (ID 174)
LuaEntity API call when LuaEntity was invalid.

Thanks for the report. This will be fixed ASAP.

This should be fixed in the newest version.

Goodness, I just hit this, someone beat me to the report, and you beat me to the fix. Thanks for the hard work on this fantastic mod!

The factorio devs set a high bar for us mere mortals to strive for :)

I forgot to add that the error occurred in the sandbox (https://mods.factorio.com/mod/blueprint-sandboxes)

Is it still happening?

No, the problem is gone, thanks

I'm still getting this in 2.0.6

The mod Automatic Underground Pipe Connectors (2.0.6) caused a non-recoverable error.
Please report this error to the mod author.

That's a different similar error. And it should be fixed in 2.0.7 now!
