I'm not sure if it is this modpack, or the add_loader in general having this issue. Does anyone else have this issue? After a short period of time the loader seems to lose any filter that is set. This isn't seem to be a problem when arumba was playing, though it is possible the pack is the culprit since he uses the mods individually.

My mod loader snapping is the culprit, I pushed an update for it several hours ago to fix this and the modpack will be updated including the fix soon. Sorry about that!
EDIT: Mod pack has been updated :)

update fixed this can confirm.

Awesome Thanks.

I had a similar problem, loaders lost their filter when belt was placed adjacent to them. not sure if it's fixed, i'm working on a problem with nanobots right now.

Cowb0t can you check if the loader issue is fixed in the latest mod pack version? I am working on the nanobots issue.
