[2021] How can I fix this bug?

Hey,

I bought Eco earlier today and started a server with friends. I've run into a few game-breaking bugs and it's a bit frustrating. How can I fix them? I've restarted the cloud server and that hasn't fixed it. Initially things were fine and then they turned buggy and I'm not sure why :s.

Doors: I can place doors, but they aren't functional and I can't interact with them at all once they have been placed. I can't see the pop up name tag, I can't remove them, and I can't open/close them. Instead, I'm able to run right through them.

Trees: Once cut down, I can't chop them up. If someone else chops them up, I can only pick up/haul away a single chopped chunk (typically 4 pieces). If I attempt to pick up more it's the same issue above. Other people can see the name, can pick it up, etc. I just can't.

Carts: It was given to me, and I was able to place it in the world (making it 'mine'). I can't put things in it or pick it up. Again, no name tag and no interaction.

Is there a config I can change? I'm the owner of the server/only admin, and I've sunk most of the day into it along with most friends so I can't exactly delete the server either unless I can somehow preserve the world? Is there a command I can use? Help!
