Minecolonies version

Version: minecolonies-1.12.2-0.10.313-BETA

Expected behavior

Don't misplace chunks

Actual behaviour

Server says: "Can't keep up!" and chunks gets misplaced
I play alone in my server, I've been playing a lot of time in a world, creating a big colony with 49 colonists. Everything was going good, but when I actualized to minecolonies-1.12.2-0.10.313-BETA, the server started to work badly and to consume a lot of RAM, (I have 8 GB and 64 bits), after that a lot of chunks got misplaced. I tried using the previous version (0.10.0312), but the problem persist. Now the server has crashed.

Steps to reproduce the problem

To reproduce it you should have my server folder and just try it
I have others mod, but in my opinion they are working fine
Craftable hourse armour
Currency mod
IndustrialCraft
Millenaire mod (millenaire villages are far and inactive)

Never was able to tie this to our mod or reproduce this. No one else reported similar either. So i guess something else was causing this

Thank for answer!, so, to sum up, I wait for the new update and this won't happen again?, I can fix those uggly chunks with McEdit, there's no problem with that

Of course!, I'm uploading it. It weighs 311 MB

It's impossible, because the world weighs much

I forgot to say that my character was reseted when that happened, I mean I lost all my inventory and experience

hope you have a backup somewhere. Its always a good idea to zip a backup before an upgrade.

I also play in a server and always got the server overloaded message every 10 secs. i read somewere that is related to ticks taking more than 50ms. You can use /debug start, /debug stop to generate a file that gives you a hint of what is taking more to process.

I undersand. My computer is very strong, so it's very strange to get overloaded. I have a very old backup, I can fix chunks with that, but I need a way to don't continue misplacing chunks in my map
