Hello there.
When i got BetterEnd (Forge) Installed and enter the End, chunks generate VERY slowly.
After some time chunks almost completely stop to generate and the server is overloaded constantly.
When i do not have the mod, this does not happen. I have ~89 other mods.

Is there something like this known? Anyone else having huge lag in the End? (Not in other dimensions)

What's up people!
I have the same problem here too. I did some testing and found out that the ''Megalake'' biome doesn't like Dynamic Tree mods. Basically every things run fine until the Megalake pops in and the rendering goes good bye. The server side is slow as hell (10 000+ TPS) but client runs smooth. Go away so its out of the render distence then the TPS drop back to normal and server side gets revived from the trauma.
