Happens for our map on server and clientside. Forge asks for missing blocks/items, creates the backup and tries to load the map. While loading the whole game stalles. Client is sitting in the MC main screen and trying to connect to a server (with stalled map) causes a simple timeout.

It only happens for our large server map. A small test world is loading fine. Could this happen if a large tank is not fully chunkloaded? After removing one large tank the map is loading, but it stalls again with the same issue.

haven't been able to reproduce after #404

What version did you update from?

Apparently I was saving the block name instead of the Block object itself, dont ask me why, I don't even know myself. I changed that, itll improve a little, but I don't think itll fix this.

If you can start the server on an older version, I recommend changing all tanks so that they don't cross chunk boundaries.

Another thing that crossed my mind, did you remove any mods that add planks that might have been used in the creation of a tank?

Well I'm going to have to something about this, so I'll leave this open.

I told my member today that everybody should respect the chunk boundries and I will also give it a last test tomorrow. After deleting the tanks in SP (testwise) it did work. So it should be ok for the update hopefully :).

The server update is from AgriCraft-1.7.10-1.3.1

€: I added Agricraft in the first weeks of July and most people only use vanilla logs. There was also no mod removed.
