Steps to Reproduce

1.set "follow_current_file = { enabled = true },"
2.open vim in a linux source code tree and open neo tree
3.run "/" find "file.c" and select by "c-n" and "" open it

Expected Behavior

This is reproducible and unfortunately I think this is very difficult to fix.

@zaiqiang-dong Will it start following current file when you go to a different file and then come back? (I assume the answer is yes) and this is the only easy way to restart follow-current-file.

I'm currently doing a rewrite that should make search and async code work smoothly so please wait till it's done for a real solution: #1340 (comment)

Thank you for your reply. Looking forward to version v4. x

I hit the same issue, even when the file name is unique. A lot of files and deep nesting leads to the follow_current_file not doing anything. Works on small codebase, but on a larger one it fails silently
