FOSS gamedev and creative worlds

i am tired of this server...i try to move than i get transported to the same location over and over....and when i place a block it all of a sudden its gone then there again....when i destroy a block it comes back

Probably your connection is not so good.
The teleport happens usually because of lag. Not being able to place blocks can be either because of lag, or because you don't have interact privilege.

my internet is fine....and the glitches have been getting worse
