In Regards to Unexplained Coordinate Changes
I've noted this inexplicable change in coordinates a few years back in a comment on a post on here as well. Here is that thread:
I've noticed it happen literally every time I leave and go back into the game. I originally had set up a prospecting grid of every 50 blocks using the coordinate display in game. So one at 0,0, one at 50,50, 50.-50, -50,50, and -50,-50, etc. Then I did the 100s, 150s, 200s, and so forth. I bet you can guess what happened to this carefully planned idea once I had begun to execute it in the world but then left and came back to the game the next day. Yep, all my coordinates were off by anywhere from 1-100 and nothing lined up as it should, essentially breaking my ability to create my planned prospecting grid. I had to change how I was doing it and ultimately resorted to using the '.debug wireframe chunk' command to setup a chunk-based prospecting pick grid where I marked the corners of every chunk with a cross of blocks and prospected in the exact five blocks at the center of each chunk instead.
I've noticed this happen with my macros I had for teleporting back to my house as well. I'll set up the macro, and it will work fine until I log out and log back into the game. The coordinates, which were correct and worked just fine minutes before now would teleport me to the same coordinates, but at a different location in proximity to my base. So, I would change my macro, but once I left and came back it was inaccurate once again.
In Regards to New Seraph Voices
The player character now sounds like a harmonica due to what seems like the permanent addition of musical instrument sounds as your avatar's 'voice', with six or seven different ones to choose from at character creation. My guess as to why yours sounds like a harmonica is that is the default instrument sound? Can Tyron or anyone who knows the game better confirm this?
EDIT: Apparently all Seraph avatar traits are randomized at the beginning. But does that also apply to seraphs that had been created already when the change took place? Not sure.
