Update: Build 128 (small hotfix update) — Wrench Steam update #855675

HOTFIX NOTES (Build 128) - Improve battery install rules. * Install battery tray onto chassis, then install battery, then install hold down and bolts. * Existing assemblies (from Build 126) should have their installations corrected automatically. - Fix incorrect input bindings for SteamVR Vive Cosmos config. - Fix bug causing parts to occasionally fall through tables when loading. - Add symptom masking. This hides symptoms as appropriate based on the engine starting or the car being drivable. - Fix 2-handed grabbing bugs in VR affecting at least the oil drain pan, funnel, and radio. - Change chassis battery bracket fastener art to rivets. (it is not player-serviceable) - Change save game backup method when loading a game from a previous save version. - Other minor bugfixes and tweaks.
