Friendly Mobs Are Gone!

[RedDemonLord 0]

Hello all!

I have a SMP server. So I updated TFC to build 76. But I wanted to keep the map. But it is kind of getting troublesome.

There are a lot of item ID issues. Like, all of our TFC planks were turned into handmills and plans are now sprindles. Metal nuggets were converted into lava filled blue steel buckets and such... Well, that's not much of a big deal, to be honest.

But the real problem is, all the animals(friendly mobs) are gone. Not sure what's happening, but those entities instantly get ignored by the server. When I try to load new chunks, this happens. Take a look:

It's gamebreaking, any ideas? :[

Did you delete the config file when you updated, on both the server and all the clients? It is strictly recommended to do this for TFC, and if you didn't, that might be where your item ID mismatches come from.

Unsure if that has anything to do with your mobs disappearing though.

I did delete the config files on my client and server.

..all the clients?

Well, not sure about my friend's though, would it matter? But like I said, main problem is that animals are disappearing. I am able to spawn friendly mobs, but only via use of cheats. Hostile mobs are perfectly fine.

There is your problem. The servers world file is looking for specific ids that it then links to specific files. If your keeping the world you can't delete the config, even if blocks and items are added.

Best bet if you hopefully have a backup, if not there's pretty much no going back, is to backup the config on your client. Then you delete the confg on the client. Then load and produce a new config with the new version. After that you have to cross reference the new config with the old one and make sure all the old block and item ids match the old config, and that any new ones don't conflict with older already used ids.

Basically the server is looking for id #such and such to be in that particular spot. So if block id it was useing for the block was 213, but now the id for that block is 235 and now id 213 is used by another block then it will show the new block with that id and not the old. Same with items, same with entities (like sheep,cows,chickens and so on).

The reason your animals poof but monsters still appear is because animals are persistant, and monsters respawn constantly if their spawn conditions are met.

Edit: reason I say generate new config for cross reference on client is if you do it on the server then the dammage is done ad soon as the world loads, animals that possibly have a new entity id are then deleted cause the old animals were not linked to an id on the world files. Once the new config is varified you can then either add it to the server, or cross reference it with the server config.

Oh? Well, can you explain why clients has a drastic effect on the server itself? I mean, shouldn't I be the only one who can't see the animals because I deleted my config? Anyway, I think I do have backups. Sorry but I must ask another thing, what is and how to cross reference?
