Hello, after numerous tests and numerous add-ons purchased, I noticed major problems when saving maps on the Realms server.

Indeed, after numerous tests, I noticed that certain add-ons completely prevent maps from being downloaded to Realms, regardless of whether add-on elements are placed in the map or not. This prevents you from doing any backup just in case.

The add-ons in question preventing the download/back-up of Realms maps would be (at a minimum):

Craftee (Craftee companion Add-on)
Telelanterns Add-on
Vehicle Add-on

Having neither the time nor the money to test all the Add-ons, here is a list of Add-ons that do not pose any backup concerns:

Myths and dragons
World utilities
Gravestone
Craft secret doors
Security
Magic spells
Grappling hooks
Furniture
Tinkers' construct
Celebration food
Naturalist
Morph gauntlet
Professional planes
Spark pets premium
Survival mech
Computers

The major problem with this is that I spend money on minecoins/Add-ons and ultimately not be able to use the Add-ons on my server... If a fixed one is available, I will take it with great pleasure ! (fixed other than: "disconnect", "restart the PC" or other, having already tried everything).

Thank you in advance for your return !

If, moreover, it is possible to be reimbursed for Add-ons preventing the downloading of Map on Realms, I am interested, being still a student...
