There is something happening on my server that I just can’t wrap my head around. Whenever a regular player uses a bucket with any liquid, the bucket does not empty.
The players can pick up liquids but the source block will not disappear. Making any liquid block essentially infinite.
Sounds like a permissions issue, try removing LuckPerms and checking, if it still happens then its not, if it doesn’t then send over your permission.
Also, not sure why but it seems your screenshot removes parts of text making it difficult to read, try just a normal print screen and then saving it with something like paint
