I think its not working anymore under update 7, could that be?

Is this going to be uploaded to mod.io? Just curious. Some people prefer using it.

chopper, the yealds are perfectly fine, and you'll have a huge overflow of it all of those. think further back, you get 8 planks from one single oak, thats plenty, and very realistic depending on the how fat you need your beams ofc. but they obviusly modify them where they build, so having fat planks/logs to work with makes sense.

It's so sad not being able to play the game without this mod currently, hoping you'll update.thanks！

Make the underground mines worth the production costs. 100x the scrap metals produced while 30x the time and 10x the material costs

使地下矿山的生产成本相等。废金属产量的100倍，时间的30倍，材料成本的10倍

Chopper get the "Dirt" mod it has both of the upgrades you are looking for.

Nice.
Can you update the lumber mill & gear workshop? Should be getting more than 1 gear from 1 plank, and 1 plank from 1 log. Most inefficient beavers ever.
