I'm a self sufficiency type. So I have been doing all the construction work on the ten buildings I started on my plot. It was kind of a kick to level carpenter, enchanter, and weaver by actually doing all the tier 2 and 3 construction work on my plot. I usually level in the most efficient manner possible: making and deconstructing tools. I rarely do any actual useful work in the craft school I am advancing. But there I was leveling a few schools from 20 to 40 by actually creating the intended product: construction applied to buildings.
Well, that phase is over now. With the vault shrunk back to it's original size, every unit carried to the plot is going to have to count. No more applying below optimum for me. Wearing the best possible cargo armor is going to be important too, now that I can't just drag a huge disk full from the nearest vault. Likely I won't even belong to the construction school while applying. I'll level it up to optimum separately on tools and then switch to my highest school and best cargo before transporting units to the site.
Ah, the life of an honest construction worker. It was nice while it lasted. Time to move on and be efficient again.
