Registering liquid, dimension, biome, and testing it works fine, But when i add something new to my mod, all liquid in world get replaced with other block. Is it because of id changes? Will this issue stay in 1.8?

What i already tried: move registration to pre init, move = new SkyLiquid to init or pre-init, hothing helped

Class where i register liquid:

package code.blocktoolsarmormod.registry;

import net.minecraft.block.Block;
import code.blocktoolsarmormod.world.dimensions.Sky.SkyLiquidFlowing;
import code.blocktoolsarmormod.world.dimensions.Sky.SkyLiquidStill;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.registry.GameRegistry;

public class LiquidRegistry {

public static Block SkyLiquidStill = new SkyLiquidStill().setBlockName("SkyLiquidStill");
public static Block SkyLiquidFlowing = new SkyLiquidFlowing().setBlockName("SkyLiquidFlowing");

public static void preinit(FMLPreInitializationEvent event)
{ 

}


public static void init(FMLInitializationEvent event)
{ 
	GameRegistry.registerBlock(SkyLiquidStill, "SkyLiquidStill");
	GameRegistry.registerBlock(SkyLiquidFlowing, "SkyLiquidFlowing");
}


public static void postinit(FMLPostInitializationEvent event)
{ 

}
}

You need to register during the pre-initialisation stage.

Registering during pre-init didn't helped, i wrote there:

Sorry, I misread. Blocks shouldn't get replaced when you ADD blocks to an existing world, only when creating a new world. Are there any messages when you run it with the new blocks in console?

Yes:

Injecting existing block and item data into this server instance
[10:32:31] [server thread/INFO]: Injecting new block and item data into this server instance.
[10:32:31] [server thread/INFO]: Injected new block/item blocktoolsarmormod:blockA: 184 (init) -> 185 (map).
[10:32:31] [server thread/INFO]: Injected new block/item blocktoolsarmormod:blockA: 184 (init) -> 185 (map).
[10:32:31] [server thread/INFO]: Injected new block/item blocktoolsarmormod:itemB: 4458 (init) -> 4459 (map).

Also i found out this: Liquid automatically turns in another block even when placed by me and updated?

Reading through BlockDynamicLiquid and BlockStaticLiquid, if found methods, that are responsible for making in flow, where to detect another state of liquid, getIdFromBlock(this) - 1 is used, its private method, and it cannot be overrided...

 

STUPID MINECRAFT!!!!! JUST BY REGISTERING STILL LIQUID AFTER FLOWING MAKES IT WORK PROPERLY!!! FACEPALM
