In the latest beta of Ex Nihilo Creatio Silkworms when used drop players fps and kick them from the server, I remember this same bug back in 1.7.10 and thought it would be fixed but it seems to have returned. I have no screenshots or logs for this as when this happens players tell me after they drop fps and crash to the multiplayer screen

A single infected leaf block produces a constant 20 block updates / tick (in F3) while it is transforming, That should be a zero, and it's a small change to make it 0.

Video of me testing a FastTESR + change in progression along with this block update change. Still get updates from spreading, but there's no escaping that. I consider my computer surviving the test to be a success.

I've also done a PR which should resolve a lot of the issues people are experiencing with Infested Leaves, especially in highly dense areas.

For record purposes Tencao's PR is PR #45.

Pull Request #45 should greatly improve FPS.

It's happening when they just use 1 at a time on my High-Tech a Sky 2 Official server

Internal exception: io.netty.channel.unix.errors$NativeIOException: syscall:read(..) failed: connection reset by peer thats what hes gets

Perhaps instead of sending the nbt with the state repeatedly, if only the end time is sent, the client could then calculate the current state to render based on that (min(1.0, (final time - current time) / total time)).

slight problem there, you can't rely on the time to be the same on both.
One possible thing to do is to lower the amount of packets to a minimum to keep it in sync every few seconds.
