That version hasn't been fully brought up to date. I got around half of the items updated and the newest stuff didn't get in yet.

any eta on when you'll bring that version up to date?

Its just been slow going so hopefully this weekend. When you say low pop, is it just you and friends? For one small community I would recommend the MP version anyway to stay more up to date. Since I added the admin box its brought that quicker crafting ability to the MP version. You would have to run both or wipe and start again but the alternative will always be a few weeks behind the MP version. My schedule changed recently so its made the amount of time I can mod a little less and the SP version has sadly been the main loser because of it.

mostly only a couple people per base. the resources required for MP parts is just too much for a couple people, hence why we are using the single. seems too cheap though, maybe change the resource requirements to 1/4 of MP

i build most stuff alone just fine. ressources compared to vanilla building is ~ 60% cheaper

ex. 1 wall in architect mod is 16 pieces of vanilla walls, but cost only ressources of 10 walls

Hogs, if single player is installed on a server, can a clean switch be made to the MP version without loss of structures?
