I used to use ConCreep but got tired of it removing it's blueprints on occasion, leaving my factory spotty.

However trying to load this mod locks my game up, it's play for about 1 second then freeze, i assume it's because it needs to run through a lot of tiles, as i have upwards of 600 roboports, but after leaving the game running for over half an hour there doesn't seem to be an end to it yet.

My log file is currently 80K+ lines of this message:

With different names on occasion, i assume it's the name of the roboport it's checking.

Sorry for the late answer, the portal doesn't notify for messages. Tried 14.3?

No worries.

I haven't had time to dedicate several hours to testing but after installing the newest update it only froze my game for a few minutes, after which it ran fairly smooth, the biggest issue being a slight lag spike when a roboport placed a round of blueprints down.

But at least it's playable like this, and I'm running the auto tree cutting mod as well and it that works too, thank you for your work.

Having had a bit more time to play around with it, it now crashes my game after a few minutes. Toggling the mod off it runs just fine, even with busy bots and tree cutting still enabled.
