Post your bugs here using the following template: Mode: Survival Mode: Singleplayer, SEED-ID: (Please always add the SEED-ID for SingleplayerSurvival games; Open the console. The Seed is noted somewhere to the "playfield loaded" dialogue) If applicable: MODIFIED PLAYFIELDS: No Reproducibility: (Always) Severity: (Minor) Type: building using symmetry mode Summary: When placing items with more than one block directly on the symmetry axis, game places two items. Description: Two items are placed on symmetry axis. both show up in the device menu. Steps to Reproduce: On a CV, start symmetry mode, with an axis running down center of blocks. select a two by one cargo box. place along axis of symmetry in the one symmetry line of blocks. two items will be subtracted from inventory. two items will show up in device menu, but only one physical item is placed.
I posted a report about this also, though mine was for an SV build. It appears that only certain devices are impacted, so, general Steel Blocks place just fine along the centre line with only one being taken, but other things like Generators and Thrusters see two taken for one placed. This is actually a fairly old issue, but it appears to have returned / not all of the cases were addressed. Scoob.
