MoveToLocation causes main thead hangings and disconnections

Every time I use this to go on a server, it is super slow and will disconnect after a few moments.

terrainandmovements seems to be the cause. See this pastebin of my MinecraftClient.ini file.

Hello,

I'm sorry but this is too vague for a bug report.

Please at least describe your configuration:

• Your operating system with version
• Your Mono version (if running Mac or Linux)
• Minecraft version running on your server

Mono JIT compiler version 4.4.2 (mono-4.4.0-branch-c7sr1/f72fe45 Wed Jul 27 16:20:13 EDT 2016)
Copyright (C) 2002-2014 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com
    TLS:           normal
    SIGSEGV:       altstack
    Notification:  kqueue
    Architecture:  x86

    Misc:          softdebug 
    LLVM:          yes(3.6.0svn-mono-master/a173357)
    GC:            sgen

Servers I've tried to use it with: Vanilla 1.10, CraftBukkit 1.10, Spigot 1.10, and BungeeCord 1.8-1.10.

My MinecraftClient.ini is in this pastebin, I am using what I think is the latest version:

Console Client for MC 1.4.6 to 1.10.2 - v1.10.0 DEV - By ORelio & Contributors

Try turning off terrainandmovements - it causes additional work to be done which may impact performance. If it's still laggy with that disabled, then something else is clearly wrong.

Also... your login info is in that config - you might want to change your PW :/

I need terrainandmovements

and dw ;) that's not my real info

[ORelio]

Indeed, please change your password immediately (and edit/delete/replace your paste if you can), to remove your credentials so that your email also does not get spammed.

Regarding the report, thanks for the details!
The platform seems good, and you are indeed using a recent build. Nice!
The only thing that I'm not sure about is Mono 4.4, MCC has been successfully tested on Mono 4.0-4.2, that should be fine too with 4.4 but I can't confirm that.

In any case, is there some specific message while disconnecting, or is it fully silent?
Does disabling terrainandmovements as suggested by @Pokechu22 helps? (even if you need it)

When it disconnects, it will say

 Connection has been lost

along with some weird, what looks like, an escape code. Something like ;45>>; from memory.

It sometimes, but not always, outputs a weird string like this: >>747;3R along with the Connection has been lost message.

And I have just disabled terrainandmovements, it seems to be working better. Maybe it will quit in a bit, but since my last post 15 minutes ago it hasn't crashed, which is the longest it's run in a long time.

However this is still an issue in that terrainandmovements causes it to disconnect.

[ORelio]

Good! That means we got a hint about where the issue is located. Just in case, please re-enable terrain and movements, and use the latest developpent build, there is a slight change for issue #217 that might help (but will proably not help, well, just in case...). If that doesn't help, I'll try to reproduce & debug your issue by using the same environment (well, at least, the same Mono version, MacOS is probably not the culprit)

Ok thank you.

Now, not relating to what you just posted, but from before:

And I have just disabled terrainandmovements, it seems to be working better. Maybe it will quit in a bit, but since my last post 15 minutes ago it hasn't crashed, which is the longest it's run in a long time.

Well, it did just crash. This was with the same configuration as when the issue was created but with terrainandmovements disabled.

I am now trying with the latest dev build as linked to by you.

And it fails again. Exactly the same as with my previous build.

Connection has been lost.

[ORelio]

Seems like there is also an "out of sync" issue even without terrain and movements. Oh, well...
