Sorry, I left out a sentence pointing at there being multiple issues, mainly refering to snapping.
I’m aware of these issues. Snapping is something which is broken because of e.g. not (correctly) being carried over to new building pieces, whereas bugs introduced in new patches have often been due to changes in assets (these are in the devkit changelog, public to modders). These issues have a lower priority than game-breaking bugs etc., but it seems that it’s gotten high enough priority;
There’s been no statement whether players can expect this to be fixed in a future update, so it’s currently being internally played around with (remember that internal testing is very limited). It may come to TestLive in the near future, but don’t expect all snapping issues to be fixed at once.
