Hi there,

I have two packages for which the build on Julia nightly keeps failing recently. For both of them I get the same error message,

```shell
[...]
┌ Warning: The active manifest file has dependencies that were resolved with a different julia version (1.8.1). Unexpected behavior may occur.
└ @ ~/work/ConformalPrediction.jl/ConformalPrediction.jl/Manifest.toml:0
ERROR: Could not locate the source code for the DelimitedFiles package. Are you trying to use a manifest generated by a different version of Julia?
Stacktrace:
  [1] pkgerror(msg::String)
    @ Pkg.Types /opt/hostedtoolcache/julia/nightly/x64/share/julia/stdlib/v1.9/Pkg/src/Types.jl:68
[...]

```

see [here](https://github.com/pat-alt/LaplaceRedux.jl/actions/runs/3228268671/jobs/5284140170#step:5:30) and [here](https://github.com/pat-alt/ConformalPrediction.jl/actions/runs/3202685097/jobs/5231919538#step:5:30) for details.

I figured it may have something to do with dependencies, but at least in terms of direct dependencies there’s actually no overlap here:

```julia
(ConformalPrediction) pkg> st
Project ConformalPrediction v0.1.0

```

Have tried upgrading the Manifests, resolving, (re-)instantiating … but nothing seems to help.

Any ideas what’s going wrong? 🙂

Looks like you’re checking in the Manifest files, which is somewhat unusual for packages, although common for projects. Is this important for your package?

Ahh I’m an idiot, not sure why/when I changed my `.gitignore`. Thanks for the quick response!
