Apparently marking a mod as deprecated interferes with modpacks automatically downloading it, see https://forums.factorio.com/viewtopic.php?f=34&t=125646. I think this is a bug in 1.1, but it will not be fixed for users of that version.
Would you mind removing the deprecated flag from this mod to fix the problem for users still using 1.1? It won't show up in search anyways since there is no 2.0 release. A note on the mod description would be useful to state that the mod is no longer being updated.
