Just got this error message after updating to Factorio 2.1.17 from 8/26 and Pyanadon's mods (normal mode Alternative Energy set) from today 8/28
Unfortunately I did both updates at the same time, so not certain which caused it, but from the error it appears to be related to some Alien Life update(s).

sw-rates-pyalternativeenergy 0.4.0 errored when running a required file.

...ates-pyalternativeenergy__/configurations/py-farming.lua:11: module pyalienlife/scripts/farming/farm-building-list not found; no such file pyalienlife/scripts/farming/farm-building-list.lua

I released a quick fix. Can't spend more time in the next 2 weeks. Hope it helps enough to continue playing.

Thanks for the quick update. Mod loads fine now. I tried doing a little testing. I haven't gotten to the automated smart farms yet, so just did some testing on the dig sites. The dig sites are a bit unusual as the rate that the dig-o-sauraus' are able to run is also affected by ground tiling. I tested without tiling and with refined concreted also with meat and worker food. For my manually timed #'s for four dig-o-saurus in a dig site I got: 35/min for meat/no tile, 46/min meat w/ tile, 120/m worker food/no tile and finally 160/m worker food with tile. If I use the production tool it displayed 1.07/s (~64/min) with meat and 4.27/s (~256/min) with worker food. So the numbers that the tool displays appears higher than I can achieve. Not sure if there is some other trick I am missing or if the numbers are off.

Currently the movement of creatures in the dig-site is completely ignored. There should be a note about this in the GUI. Just overbuild them a bit and put refined concrete down for faster walking speed. The important part is the food-to-nexelit ratio and that should be correct.
