Okay, I have a glitch and fix to talk about:
First off, love the hell out of this mod, I am not sure I would play valheim as much as I do without it, so thank you.
Anyway, I go and builda massive ship (think cruise ship size), throughout the process I test its stability by turning on and off raft creative mode to see if parts break away (for some reason they don't always get attached to the raft base). In a previous build, I finished the entire ship without checcking this, and when I turned creative mode off...well, the ship spun in a circle at super sonic speeds, then exploded. I eventually found parts of the ship embedded in the world space...so now I have a landmark...best glitch every imo XD.
Anywho, this time around, I checked it periodically, had a few pieces that needed to be fixed, but everything seemed to be going okay...seemed.
I turned on godmode at some point (probably because I was jumping long distances and didn't want to die), so when I turned creative mode off for the last time...well...things went pear shaped.
For some reason, the raft just didn't float...like at all, it sunk to the bottom of the ocean and then started to drag itself forward breaking the land.
I immediately turned creative mode back on, and because I had godmode on, the boat didn't explode this time (luckily). I did a frantic search of the ship, and no damage had actually occured (godmode). So...I got back on the wheel and turned off creative mode again, ship sicks, but starts turning in space. So I turn off and on creative mode several times to at least get the boat facing the right direction, but it wouldn't float.
Frustrated, I flew around the map using flymode, to see if reloading the general area would fix the issue. Noting I had left raft creative mode on.
When I cam back, the boat was floating without issue!
I immediately jumped in and sailed it out towards the open sea so as to get out of that grid...but no idea what was going on.
Anyway, here's my boat: https://imgur.com/a/BEi0Xc0
