Series of bugs

Hello, here are some bugs that I report to you following a multiplayer survival adventure.
It may be that some things may be normal.
List of bugs:

• You can take the fire through the shield when receiving an arrow.
• Unable to defend with sword
• Damage of High drop in abnormal cases.

That's all for now, sorry if the mail is not spelled correctly.
I am French.

Sincerely,
Lionel (Lioch)
