Implemented Gravestones + Right Click + Skyblock = Disaster

So after a recent mishap in Thaumic Skies, it was suggested I come to the forum with my idea. Starting off, I should explain what happened. After falling off my island into the void, I ended up dying and my gravestone spawning by itself. Using a water bucket to get back down to it, I tried to build a platform around it. Unfortunately, instead of a block placing down next to the gravestone, right clicking ends up breaking it, allowing all my items to fall into the abyss.
Now you know why I'm here, so here's my suggestions. Disabling the setting that gravestones will break with a right click in skyblock, or make it so gravestones only break with a right click as long as you have an empty hand (which would be very amazing to have in every other modpack, I have lost my things to this before.)

Thanks for your time.

 

Would also help if the gravestones get placed at Y2 so that a dirt block can spawn just beneath it (Unless that already happens? I haven't fallen into the void yet so I dunno)

 

dirt does spawn

 

It would spawn the dirt block if its enabled, but its usually disabled on skyblock servers because it allows for an easy quick way of getting dirt
