Create Table Cloths spams Interact message upon hovering on it.
I can use the table and shop mechanic with no issues but its really annoying when I just wanna hover my mouse on it.
Any ideas how to fix this ?

I did added the create:*_table_cloth on forcedBlockProtectionExceptionList

I forgot to mention that I am on Neoforge 21.1.209
OpenPac is on 0.25.6
and lastly Create on 6.0.6

Interesting. I guess Create is just spamming packets when you hover over it.
create:*_table_cloth probably doesn't actually match anything, btw. Check the block ID on the F3 screen.

I'm having this exact issue. I've tried a several variations in the configuration to try and get this working to no avail.

forcedEntityProtectionExceptionList = [ "minecraft:minecart", "#create:table_cloths", "interact$create:green_table_cloth", "create:green_table_cloth" ]

itemUseProtectionExceptionList = ["minecraft:firework_rocket","#create:table_cloths","interact$create:green_table_cloth", "create:green_table_cloth"]

open-parties-and-claims-neoforge-1.21.1-0.25.6.jar w/ Create 6.0.6

I attempted doing the same concept with signs. E.g blockProtectionOptionalExceptionGroups = ["Signs{minecraft:signs, #minecraft:signs} and toggling this to "OFF" in server claim settings, yet it's still "Not Allowed to Interact".

@T3tr3x Adding the table cloth block id to entity and item exceptions wouldn't do anything, it's a block.
minecraft:signs is not a block ID, the only thing correct in that sign exception is the block tag #minecraft:signs, which should work. Setting the exception to OFF turns the exception off, which is not what you're trying to do.
And make sure using minecraft:diamond is allowed in item use exceptions.
