StructureTemplate placement still off at times

[Cervator]

This probably came in via ST changes made during GSOC 2018 but I'm not sure. Some of those changes were salvaged from old PRs, so the possibility for bugs was higher than usual. At first seemingly all STs failed to translate their world coordinates right and ended up squashed together around 0,0,0. Later after @Naman-sopho found a fix for that (yay!) it still seems like they're not adjusting to the world surface very well:

Unsure if this is specific to placement in DC or a general issue with STs, but GooeysQuests seems to manage to place its ST segments lined up decently still.

While testing #39 the building placement looked alrigth (sligthly off sometimes, but now floating or underground buildings).

I'll close this, please feel free to re-open in case it happens again...

Tested out some more with recent fixes - seems to be entirely complete now, huzzah! Closing (again) as complete
