Some bugfixes and a particle effect to make it clear that parts disconnecting during the build process is intentional, not a bug. This update is on the beta branch. Switch to the beta branch in Steam to try out these updates before I push them to the default branch later this week.
Changelog
Improvements
Added a particle effect for when parts disconnect during building, if they've not been bolted down and too many parts are attached to the assembly. Yellow sparks will fly where connections are broken. This is intended to make it clearer that this is intentional, and not a bug.
Bugfixes
Fixed a bug where if the game failed to update a subassembly's collider, it would get stuck trying to retry that update, causing massive lag.
Fixed a bug where parts were placed in the wrong part of the hierarchy when the player attaches them in a specific way.
Happy skies!
