@kvor - Are there any errors from the Apex Language Server? See https://github.com/forcedotcom/salesforcedx-vscode/wiki/Apex-Language-Server#are-there-any-errors-from-the-apex-language-server

@vazexqi No. Output is clean.

Does this happen when you have a type (custom object, standard object) that it doesn't understand?

Have you fetched the sobjects using https://github.com/forcedotcom/salesforcedx-vscode/tree/develop/packages/salesforcedx-vscode-apex#enable-code-smartness-for-sobjects?

In any object. After restarting VCS, it works perfectly.

Yes, if I have an issue with autocomplete, I try to repeat the fetch process as described but with no luck.

When it happens, it is usually fixed after VCS is restarted

@kvor - What restarting does is that it clears out the database (you can find it under .sfdx/tools/apex.db). That seems to imply somewhere that we have gotten into a weird state with the analysis. However, the fact that no error shows up in the Apex Language Server output window is weird though.

Some things to check:

1. Are you running multiple copies of VS Code on the same project? Or could you be running the old Force.com IDE 2?
2. Is this an SFDX project (or did you do the trick in Support for Change Set Based Development #123 to enable the language server)?
3. Were you switching Git branches when you were coding?

Sorry, this is a bit hard to get a repro so thanks for your patience.

@vazexqi

1. No. One instance/copy of VSCode. Old IDE is not even installed.

2. Yes it is an sfdx project.

3. Yes switching git branches is a quite frequent action. Any chance that connection to apex.db is lost? .sfdx folder is on .gitignore
