Pack version: 0.4.3
Serverside additional mods: Starlight
Clientside additional mods: Rubidium, Rubidium Extras, Starlight
Reproducability: unsure

After some time of the server running, breaking blocks with an empty main hand causes them to drop as if they were silk-touched.
e.g. Leaves, Grass blocks.
This is a real problem as it causes Fast Leaf Decay to drop all the leaves as blocks rather than decaying them to saplings.

The only stuff we've built in theworld is some mekanism machines, a few thermal series machines, and two MineColonies colonies.

Does the issue persist after server restarts?, and can the issue be reproduced without starlight on your server/client

#847 also encountered the same issue, without Starlight

No, does not persist on restart. I haven't tried reproducing without Starlight, but it changes the lighting engine, it doesn't touch anyone of that ilk, so I seriously doubt it's the cause

Any progress on this? been noticing it affecting my MineColonies foresters as well, even with "Use Shears: No" in the forester settings, they end up with the leaf blocks, filling my warehouse

Updating to a newer version of the pack seems to have removed this complaint from my player base entirely.

So it was a bug from one of our 300+ mods, and we have no idea which one updated to fix that then?
Cool.... i guess this could be closed then, unless anyone has this still in pack version 0.4.17+

I also mentioned this in 847.

My players have reported this problem as well.

I also experienced it but after running a /reload for something unrelated I noticed it was no longer present.

I'll probably make a pull request should I find the issue.

Closing as no further reports
