Multiple Issues when using JEID's in large modpack. (UndergroundBiomes & Issues with Hell Biome)

[KirinFuji]

Hello, I have been building a large modpack and had to switch to using NotEnough IDs due to issues from JEIDs.

UndergroundBiomes: When any custom gravity block from UB (Eclogite Sand, Eclogite Gravel, Etc) falls the falling block renders as a random other block. For example, when the blocks would fall I would see upside down nether stairs until it hit the ground and materialized back to Eclogite Gravel.

Hell Biome replaced with Plains Biome: When I entered the nether to check on things, the Hell Biome was not there, instead saying it was a Plains biome. This caused none of the nether ores to generate and overworld mobs would spawn.

Both very strange issues, however they seemed like some kind of Biome ID and Block ID issue so I disabled JEID and enabled NEID and both issues were fixed. I am writing this to inform you that there are some issues with how things play along with JEID.

I deleted the world file before and after as I am just building and testing things right now.

I can confirm this with Underground Biomes and falling entities.

[SakuraWuhen]

I have the same problem in TFC, the blocks will be replaced with random blocks, even directly displayed as air, but right click will return to normal

The current test found that using jeid version 1.0.3-50 and below can avoid the problem

[OjGrooms]

Had this issue with ONLY Biomes'o'plenty and JEID installed in a server. JEID breaks something in the biome gen, without any clear way to solve it.

How to reproduce: Run forge server MC 1.12.2 with BOP and JEID. Set level-type to BIOMESOP. Join world from client with the same version of BOP and JEID. Check the F3 info and fly around. Biomes will look like they are trying to generate properly, but any features (trees, plants, biome specific mobs and creatures) will not generate correctly. Either it will spit out random biome names as you fly around, or will only say 'Plains'. As far as falling block issues went, I did not test for it as my concern was the bad biome generation.

[KirinFuji]

Nice find, I also was using BIOMESOP world generator type which certainly explains the biome id issues. As for the rendering of falling entities, I suspect the client and server have mismatched ids for the falling blocks leading to a client side desync until it reforms as a normal block.
