@Pantera @Hummel-o-War ; Hey guys, Think I found another issue with the most recent release (2524)... My blueprints are screwed up. I started a new game with today's release, played for a while and then built my "Tactical HV"... a reasonably large HV with LOADS of modules/devices installed. My meticulously organized (yes I am a bit OCD that way) Device List was completely screwed up - the Core in the "Engines" group and renamed Emergency Kit (from one of my cargo containers), almost 100 devices stripped right out of their groups, and in many cases all assigned signal logic was either missing or transposed with other devices incorrectly. Hate to beat a dead horse here, but in combination with my issue with ghost key presses (that you have deemed "not a bug", despite it only occurring with Empyrion running), but can you appreciate the coronary-inducing level of frustration involved in trying to re-group, rename, and reassign signal logic to over 100 devices... all while your computer is randomly pressing <Delete>, <Up>, <Left>, <Home>, etc. etc.??? ... I'm surprised my computer survived the night without taking a voyage out my window. I went through regardless, and redid the entire device list (in Creative Mode, as for some reason the key presses seem less frequent there), saved the BP under a different name... jumped back into my game and spawned it... and boom! Same issue appears again. I have save games in all 3 stages (first discovered in game, fixed in Creative, re-occurring back in game again), if you need them. UPDATE: I am noticing the same problem on multiple blueprints - I've got a LOT to go through, but so far, based on create date for the files... it seems to be affecting BP's created around June 30th on... I spawned a BP created on the 25th of June and no issues. UPDATE 2: Spawning the messed up BP's in Creative, deleting and reassigning all group, signal logic, etc. then re-saving under a new name/BP does nothing... when you spawn the fixed/renamed BP again, it's back to messed up. UPDATE 3: I'm finding that I CAN spawn older BP's without issue, and I can spawn an older BP and make changes to device groups/signal logic and resave, respawn, and no issues. I'm guessing some header record or schema layout line is written out at time of BP creation? Has that changed in/since 2517? Even a single character error in a layout/header record could account for what I am seeing... just thinking out loud here.
