Keep losing session periodically

[enoryw]

I keep losing sessions periodically, how should I go about debugging this? I autostart a terminal started with tmux that runs multiple nnn instances each with their own sessions. I don't explicitly manually quit the sessions on system shutdown (I know nnn doesn't (can't?) save its sessions if nnn is terminated externally i.e. not manually quitting the sessions with a Q) but I already saved sessions manually and they are restored as you would except until eventually the session is lost/reset. I also restart the tmux instance on occassion which "abruptly" restarts nnn instances (again, this is usually fine).

I do use make O_CTX8=1 O_NERD=1 O_QSORT=1 O_NOX11=1 but I don't think that should increase additional risks of losing sessions so I'm curious if there are any known ways a session may be lost/corrupt.

nnn doesn't have logic to delete session files. They can be updated.

Are the session file deleted? If not, probably they are being overwritten by difference instances of nnn.
Please check if multiple instances use the same session name.
