I put together a custom pack so this is probably just a mod compatibility problem, I guess I'm looking for tips or clues more than reporting an issue. However, if anyone can reproduce this with the mod by itself, or the error is on binnie's end, hopefully it's easy to fix.

Rocky hives never drop anything - no bees or combs. I've tried using normal scoops, scooperators, or just breaking them.

Every other forestry, extra bees, and magic bees hives are dropping correctly.

forge-1.12.2-14.23.4.2705
forestry_1.12.2-5.8.0.319
binnie-mods-1.12.2-2.5.0.167
careerbees-0.4.0
MagicBees-1.12.2-3.1.10

I mistook the More Bees rock hive as the binnie's rock hive.
