I’m using [agents.jl](https://juliadynamics.github.io/Agents.jl/stable/) to create an ABM. Looking at the help for [GridSpace](https://juliadynamics.github.io/Agents.jl/stable/api/#Agents.GridSpace) I should be able to search different distances for each of the dimensions in my `GridSpace` (assuming `metric = :chebyshev`) with functions `nearby_ids()` and `nearby_positions()`. For example, in the wolf-sheep-grass example model I should be able to get all the positions within distance 1 of a given agent in the first dimension and distance 2 in the second dimension with the following:

```julia
sheepwolfgrass = initialize_model()
nearby_positions(sheepwolfgrass[1], sheepwolfgrass, (1, 2))

```

But the above returns the error `ERROR: MethodError: no method matching bound_range(::UnitRange{Int64}, ::Int64, ::GridSpace{2, true})`

If I just want to search the same distance in all dimensions it works fine, e.g.:

```julia
nearby_positions(sheepwolfgrass[1], sheepwolfgrass, 2)

```

I’ve obviously got something wrong, any tips as to how I can search a `GridSpace` using different distances across dimensions?

Seems like a bug, but without runnable code or pkg versions I can’t say much. Please open an issue at Agents.jl github repo providing a MWE that reproduces the error, the full error stacktrace, and the package versions you used. If you use Agents.jl version that is not the current latest stable, first update.

Apologies it took me awhile to get back to this. After updating to the latest version of Agents I was still getting the error so have now opened an [issue](https://github.com/JuliaDynamics/Agents.jl/issues/1053) with MWE.
