MinecraftForge VS GeyserConnect

I found this. Give it a good read. It's kind of old but there might be some kind of help in there. https://github.com/MinecraftForge/MinecraftForge/issues/7558

it crashed bcz of Error java.lang.reflect.InvocationTargetException, probably mods. Also there is Duplicate key exeption, i dont know what caused it - there is a guys on github which had the same issue, try asking for their help: https://github.com/MinecraftForge/MinecraftForge/issues/5556

Does this happen in newly created worlds? Forge had an issue that was patched that caused the removal of dimension mods to break worlds. However it should be working in forge post v43.1.

I looked in LivingEntity and it looked to me like water movement physics are still hardcoded to affect all non-lava fluids in the travel function. https://github.com/MinecraftForge/MinecraftForge/issues/8608 is listed in the fluid API commit as the go-to source for info and it mentions a "fluid motion" setting but I don't see it. I get the feeling the documentation is outdated but that's literally the only documentation I can find anywhere about this api. Very frustrating.

According to this PR, it's been fixed but it's still present in 43.2.2.

That being said you can just deploy it yourself and not use someone elses.. https://github.com/GeyserMC/GeyserConnect

I only have experience using Geyser on a server so I don't know much about this, but you can look into GeyserConnect.

If you have a computer handy and a Java Edition account, you could try GeyserConnect (watch out if the server has an anticheat, anticheats don't like it). Otherwise, I'd just ask the owner to set up Geyser and Floodgate.
