When throwing an item I get disconnected from the server. After the disconnect I can re-connect right away.

Minecraft 1.10.2
Forge 12.18.1.2089
ItemPhysic Full 1.3.3 mc1.10.2 and CreativeCore v1.6.3 mc1.10.2

Disconnect error on server: http://paste2.org/s7GJpZNC
Full server log: http://paste2.org/7C3ptaBc
Client log: http://paste2.org/cvXf8FK8

Please try to use another Forge version, i suggest to try it using '12.18.1.2076'. It seems to be an forge issue.

Same issue here. It works without an issue on local singleplayer. Getting the same error as above. Lite version works fine!

Could you try out if the newest version of CreativeCore fixes this issue?

Works now. No crashes at all. Throwing works and pickups too.

Nice, i have released this new CreativeCore version, so there shouldn't be a problem anymore. Thanks for helping out.
