MC Version: 1.20.1
Flan's Mod Reloaded Version: 0.2.147
Issue/s:

• Blocks introduced by the mod such as the gun modification table do not endorse a tool to mine them (The Jade mod usually indicates if a specific block should be mined by a specific tool, and I have noticed that the blocks from this mod do not have any tools assigned to mine them)
• The blocks take a long time to mine (by virtue of first issue)
• The blocks do not drop any item when mined (possibly due to the first issue, its like trying to break stone with your fists or with an axe)

With current code, the Gun Modification Table is the only mod block that has these issues, and it did indeed not have the mineable/pickaxe tag applied. Pushing a fix now
