Issue description

I know that a similar issue exists, but the issue wasn't labeled as a bug, which it clearly is.

Short explanation:
When we (friend and I) try to assemble a boat, it disappears and it's only possible to bring it back after (I guess) somehow reloading the objects. But even then, it's not possible to move the ship after right clicking and mounting.

Longer explanation:
It was kind of weird. First only I didn't see the assembled boat, but after a while and restarting the server several times, my friend couldn't see the boat either.
When only he could see the boat, on my side mobs were affected by the collision of the assembled boat and I could temporarily ride along with a vanilla boat if placed inside the invisible ship. (I was otherwise not affected by the collision and just fell through to the ocean) But just temporarily, as the vanilla boat sank into the ocean and kicking me out of the boat after traveling a few blocks.

It would be awesome if this bug could be fixed somehow!

I have tested this with only the required mods of this mod and the problem persists.

ADDITIONAL INFO
So it seems when I die or relog (I guess when the object have to be loaded again), I can see the boat again. I can right click and mount. But it does not move at all. Disassembling and assembling turns the boat invisible again.
