Reloading modules, yes, otherwise we cant tell which modules need changes after one of their module dependencies have changed. However, that should be fast, comparable to a `:r` in ghci...

> * Use of Template Haskell > * Use of hs-boot files Yeah, both of these are not well supported and cause regular problems :(

Stack Trace: ``` *** Exception (reporting due to +RTS -xc): (base:GHC.Exception.Type.SomeException), stack trace: HscMain.hscCompileCoreExpr', called from HscMain.hscCompileCoreExpr, called from TcRnDriver.tc_rn_src_decls, called from TcRnDriver.tcRnSrcDecls, called from HscMain.ioMsgMaybe, called from HscMain.Typecheck-Rename, called...

While there are ton of stacktraces, too, loading the file `hie-plugin-api/Haskell/Ide/Engine/Cradle.hs` succeeds. I will test if removing the dependency on `Paths_` module fixes the problem.

@mudsam @dpvanbalen There should be a loading message in VSCode, or lsp-client of choice, does it get stuck on a specific Module? Can you reproduce it (with latest master), with...

So, I think this issue is related to Template Haskell. Will need more investigation.

It is very subtle, on your example, it works for me with cabal and stack. However, I get messages like: `2020-01-26 21:03:14.499238735 [ThreadId 97] - Source error on cradle initialisation:...

I am sure that it is working, I tried changing code, hover etc... You don't need to check anything, I *know* that this is an issue on linux, I initially...

Ironically, I can reproduce it now on the Haskell IDE Engine Code base, stuck on `Version.hs`. This is a huge example though.

It might be a race. When I was compiling stuff while trying to reproduce the bug, it didnt happen. The moment I stopped compiling (e.g. stopped maxing out my cpu),...
