Summary: If a gvector or quaternion value is present in your system notes for a real system, then the notes will fail to automatically load.

Steps to replicate:
- Modify system notes for Sol II (system1notes.txt) to contain a gvector or quaternion value anywhere. Example: "[1]="example note",asdf=gvector(1,2,3)". Also occurs when "gvector(1,2,3)" is replaced by "quaternion(1,2,3,4)".
- Start the game, log in, and enter the universe.
- Go to nav screen. Observe that the note for sector 1 is missing.
- Execute "generalprint(LoadSystemNotes(1))" to see that the file can be accessed.
- Execute "generalprint(spickle(unspickle(LoadSystemNotes(1))))" to see that the notes can be loaded by unspickle().

Effects:
- Only occurs if a plugin or console command adds a gvector or quaternion to a real system's notes. AFAIK this does not occur during normal VO operation without plugins.
- Prevents player from viewing their notes for that system.
- If player modifies that system's notes in any way, then original notes (the ones that failed to load) will be lost/overwritten on disk.

Tested 2024-11-10 at roughly 6:30pm PST (just now).
Windows 10, VO version 1.8.715. Tested with plugins disabled (renamed "plugins" dir to "plugins_").

Okay, thanks for the heads-up. A few questions..

- Can you tell us more about the use-case? Are you storing asteroid locations or something? Is there a particular plugin you can link to that demonstrates the intended case?

- Have you looked at your errors.log, when this happens? It may say something about the Lua sandbox not having those functions and datatypes being available.

I don't have a specific requirement/use-case for this - I was messing around trying to find out more about spickle()/unspickle() when I discovered it by accident. I remembered ye olde ticket 6310, which implied that there was some special processing happening during automatic systemnotes loading, and tested it out. That's how I found out that gvector/quaternion isn't loaded in this situation.

errors.log from (boot up / log in / enter universe / quit) from just now, using the gvector example (plugins disabled):
