Done Ender Quarry Disappeared (Need a mod)

Just had a restart on server and my ender quarry, chest, ender markers, and tesseract all disappeared. Please need a mod to investigate. Took me forever to build this stuff.

 

Did you placed before a server restart or client crash?

 

Before a server restart everything was placed and working just fine

 

Did you place them after the restart first warning?

 

Make a ticket and what server

 

Please let us know what node this happened on and the coordinates of the location as to where it happened along with the world.
You're also able to do /ticket in game which will automatically provide the coordinates and location as long as you stand in the place when running the command.

If you create a ticket, please mark this post as done. Thank you.
