i built the mining gadget in a single player world modded 1.14. i placed it in the block where you add upgrades and i went mining to get diamonds for the charging station. when i got back the gadget vanished. poof, gone, disappeared. and i checked ALL my inventories (not a lot) and no where to be found.

Also is it possible to make it mine with normal click somehow?

I'll see if I can get it to happen again

it could have also been a fluke since it happened the one time so far

Fixed in 1.15.
