Hello, I happened to find a bug while messing around in a modded survival minecraft server that I'm hosting for some of my friends. I was riding around on a boat on some dimensional tears while in the end, and I went into a waterfall sinking the boat. From what I can tell, what proceeded to happen, I was teleported back to my spawn and everything seemed fine. The next time I went to the end, it was unplayable, there was a ton of ping lag, with blocks taking between 15-30 seconds to break/place. Looking at what was happening on the server, it seemed that the boat got teleported as well, and considered itself to still be ridden, so it was keeping it's chunk still loaded (at least while I was in the end). It was causing the server to overload, it didn't crash the server, and everywhere but the end was playable. I ultimately resolved this by deleting and allowing the server to regenerate the entities folder in the DIM1 (end) folder. So the boat was removed from existence. And all seems to work fine now. Anyway, I suppose it's more a suggestion that perhaps if a boat gets flooded with dimension tears, perhaps it should break the boat to prevent this issue. Hope this is helpful to someone someday.

Other Mods:
Honestly there's a lot, and I'm a bit lazy. The modpack I created has 199 mods in it and I don't feel like writing them all out. I apologize for my laziness. If this is somehow caused in conjunction with another mod then, whoops. The only other one I could think that it might have interacted with is modernfix, as that was what I saw pinging that it was trying to skip the loading of the boat in the log.

Reproduction:
I haven't personally tested yet to see if it's reproducible. But it seems like it should be.

1. Get in boat
2. Take boat into dimensional tears waterfall
3. Profit (lag)

As an update. The damage has been done, and the amount of data stored in the chunk that it continued to save over and over during the boat incident does eventually wind up entering the lag cycle again. So I'm going to have to reset my end.
