Steps to reproduce
I sync a vault between laptop and android.
Using the laptop: I copied an entire vault (vault 1) and placed it inside a folder located in vault 2.
I also copied the .obsidian directory of vault 2 without realizing it.
It synced to the phone using your sync plugin and I could see the files and navigate the wiki links on both the phone and the laptop.
After navigating a few links, the note content was blank; no text in them (I know they contained text previous to copying vault 2). The file names where untouched. No version history was available, allthough I could open the windew where you normallt can view them.
I deleted the .obsidian directory from the copied vault 2, in case it caused issues. The problem wasnt gone.
Notes created directly from vault 1 seem to have no issues.
Expected result
Vault 1 treating vault 2 as any other folder containing md files.
Actual result
described in “steps to reproduce”. sorry 
Environment
