I got this mysterious error on github:
```julia
Got exception outside of a @test
On worker 2:
UndefVarError: `#323#326` not defined
```
along with other two very similar errors.
What is really strange though is that locally everything works fine. These are the CI logs: [new internal API for sampling · JuliaDynamics/Agents.jl@af9b3a8 · GitHub](https://github.com/JuliaDynamics/Agents.jl/actions/runs/7521387289/job/20472784488#step:7:1119)
Maybe related is the fact that all three test failing on CI are all in parallel code. However when testing locally no test fails so I’m a bit confused.
Do you have any idea on what could be the cause?

very strange, I finished up another unrelated PR and it contains the same errors on github, but works fine locally as the other one
