Whenever i am on a boat and got launched to the air by a piston the boat stops and laggs for a few seconds before being finally launched and loosing momentum. The console show this error: [03:11:53] [Server thread/WARN]: Boat (vehicle of Rudston) moved wrongly! 0.2979536341565563
[03:12:04] [Server thread/WARN]: Ignoring unknown attribute 'forge:entity_gravity'
[03:12:06] [Server thread/WARN]: Ignoring unknown attribute 'forge:entity_gravity'
My server has no mods and my internet connection is good. I tried downloading the server and playing in single player and the error doesn't replicate so the problem is the server. Does anyone have any idea of how to get rid of this error?
