Concreep is currently overriding farm tiles on Gleba (both natural and man made).

If possible, not overriding those tiles would be ideal. As a stop-gap measure, the ability to disable concreep on certain worlds would also fix this.

Thanks for the report! I'll try and get something out tomorrow to fix that. I'd already been considering a per-surface disabling mechanic, and I might see if I can come up with something else as well.

So, I've been digging through my options this morning. At minimum, I can have it skip artificial tiles, and I do intend to add the per-surface toggle.

If I can figure out a good list of natural tiles that should be excluded, I'll probably add that as well.

Fix is out with settings to disable running on specific surfaces. Haven't found a good way to do the per-tile exclusions yet, but I'm still working on it.

Thanks for that, it fixes my immediate issue. Covering Gleba with concrete will just have to wait a bit longer, but at least I can do the other surfaces.
