Gardens are no longer instant-break when punched. They have the same block harvesting speed as dirt blocks do when punching them with an open hand. Doesn't appear to have an applicable tool to harvest them either.

Minecraft 1.12.2 with Forge 14.23.0.2552
Harvestcraft v. 1.12.2a

Not sure if this was an intended change or not.

Yep, very anoying.

When using mod ore excavator and harvesting gardens (in natural form, not crops) it breaks all gardens, but to inventory comes only 1 - pls fix that.

In my experience, shovels are the applicable tool for digging up gardens.

Fixed in 1.12.2d
