Singularity containers are built but not available at BioContainers

[Swindle98]

I've been trying to track down a singularity image for hostile (v0.4.0, but this is present for all versions).
The biocontainer registry entry for hostile contains only info for bioconda and docker options. No singularity options.

The image is available at: https://depot.galaxyproject.org/singularity/
(https://depot.galaxyproject.org/singularity/hostile%3A0.4.0--pyhdfd78af_0)

Does this means that its building but the Biocontainers registry just isnt updating?

singulariuty containers are present for other images on the biocontainers registry.
