Hi!
I had a similar issue and managed to narrow it down somewhat. Unlike you I was using this mod from the beginning, but mid-game decided to install AAI loader to replace another loader mod I had to that point been using. I have no idea why that mod specifically doesn't play nicely, but this issue then emerged for me, with random buildings being 'overloaded' despite no beacons at all being in range.
Removing the mod fixed the issue, and starting a new game the two mods now play nicely together.
I'm in a K2 run, which has AAI loaders automatically installed. I removed them partway through, so I doubt that that is the issue. One thing I have noticed, though is that, if I set up a factory line in a Factorissimo building and then pick up that building and set it down somewhere else, all hell breaks loose and I get the randomized overload situation.
