I was having the pipes not showing up after adding the pipes tab due to invalid brush type. I have prodded all the construction tab mods and decided (horrible decision) to combine everything into one unified mod. If you want the consolidated mod JWeezy let me know.
48 hour later edit
I rewrote the script in the store extension mod. There is around 500 placeables and that plan will take a few weeks to do properly.
I also made them functional (mostly). Slurry can move from animal pens to the bga using the pipes. Hydrants will allow water filling (free and faster if pulling from water source)
The functionality is an external mod. I may share it later( needs lots of testing) if i have enough reason.
