These are the errors that got spammed in cmd. In case that helps
When you entity speed there is something odd at some point. As far as I understand the server sends a packet that Re:Minecraft or probably rather the packet API doesn't know. I haven't figured out how this packet is caused. (I'm not sure but maybe it has something to do with god mode). You basically can't really do much then. you can place and break blocks but can't ignite crystals or kill the pig in any way. So you are stuck on your pig. (only suicide helps I think).
When you relog, even though you are not on your pig anymore you still can't do anything. New chunks won't load for example. I noticed that it must be because you stay at the position where you were. because when you drop items they fall from there. You can still walk around. Though only on the client side.
To get out of this you have to join with vanilla Minecraft after that you can use Re:Minecraft again.
