I missed the warning that wires were deleted in the latest version for hours, which caused... problems. :sigh: Could you please add an alert for any towers that don't have wires attached to them? (They don't work unless they are part of a circuit network anyway.)

Dang, I should have known that the text warning wasn't going to be enough ;-; Sorry again for the inconvenience
I'll try to add alerts for Providers and Requesters

Alerts added in 1.4.6
Out of interest, how bad of a problem did it cause?

1. Working great now, thanks.

2. I use the Krastorio 2 air purifiers to keep my pollution under control to minimize increases in the evolution rate. Because none of my mines were receiving air filters due to the bug, my pollution exploded. What made it MUCH worse is that I am trying to get the 'Keeping my hands clean' achievement of destroying the first nest with artillery--which I won't get until I travel to Vulcanus--and so my base is surrounded by DOZENS of pacified nests that all absorb pollution. Before I realized what the problem was, the evolution rate had already climbed by about 8--not good.

OK, that's incredibly frustrating. Especially the evolution factor
I've avoided doing that achievement because of how tedious it can be, and having it be made harder by a mod that supposed to make it easier is... Not great to say the least

I don't see myself having to make any more updates that will break previous setups, so it should be stable going forward. And even if I have to and can't fix it during migration, I'll try to make the warnings more obvious
Don't think getting hit by the only landmine makes it any better though

That was certainly annoying, but not incredibly frustrating.

What WAS incredibly frustrating was realizing that, somehow, I had destroyed a biter nest and never noticed it over four hours, and the last major save was from TWENTY hours before. AAAAARGH!!! It took me FAR too many hours to slowly copy my newest base over to that old save, but I'm mostly back up to speed again.
